I haven't tried the canon PSC-3000 case, but I was researching it until I found this review. Then I gave up

and decided to look elsewhere:

Canon, You Failed Me!!!!
Jul 25 '03
Pros
Well. . . the logo on the front looks cool.
Cons
Awkward, difficult to use, and ugly.
The Bottom Line
Not only is this case cosmetically obnoxious, but in my experience this case is extremely inconvenient and troublesome to use because of its sub-par design.
Full Review
After looking around the web for a while, I bought this case for my Canon Powershot G3. Honestly, I did a bit of research before I bought this leather, semi-hard case (I looked around Epinions, I did searches on various forums, and I even read the description that Canon provides on their website). I figured that it was the OFFICIAL Canon case for my camera—how could I go wrong with it? After I finally found a good price (about $25), I ordered the case online and waited eagerly for it to arrive. When it came, I was a bit amused and befuddled because this case is completely unlike what I was expecting from studying the pictures online. After holding the case in my hands for just a under a minute, I realized that I wish somebody had written a review of this thing, because I never would have bought it. Hopefully, this review will help you make a better-informed decision on Canon’s PSC 3000 “Leather, Semi-Hard Case” (which is the extent of Canon’s description of the case).
The case has a sleek, black leather exterior. The outside of the case is crafted with black leather (which is a very sturdy—the description of “semi-hard” is extremely accurate). The interior of the case is covered with a soft cloth that will prevent scratches to the camera. On the front of the case is a silver medallion, with the “Canon” and “Powershot” logos. The case claims to be the official case for the Powershot G3 (this is stated on the box), but owners of other cameras in the Canon Powershot G line (G1, G2, and G5) say that it will fit decently (I have only tried the G3). The best thing I can say about this case it that it is well-made. When I hold it, I really do get the impression that it is quality workmanship.
The case is much smaller than I expected. It is approximately 3 inches high, 5 ½ inches wide, and 4 inches deep. If you are familiar with the cameras that this case was made for, you realize that this case is just about the size of the camera. This was my great surprise: the camera actually attaches to the case (I will try to explain how).
The case is actually two completely separate parts (a base that attaches to the camera and a hood that attaches to the base). The base of this case screws into the bottom of the camera, where you would usually attach a tripod. The hood of the case than attaches with two snaps and one piece of velcro to the base of the case. There is no strap or handle for the case; instead, the neck strap of the camera sticks out either side. Yes, it is slightly confusing—unfortunately, a picture of the case does not show how this works (unless, the picture shows the two pieces separated).
The result is a leather case that snuggly fits around the camera. Even though the case does fit snuggly around the camera, I find the case a nuisance and inconvenience to use for a number of reasons:
· While the leather protects from dust, there is no padding to protect my valuable camera from bumps or jolts (You do not want to take a trip with your camera, relying on this case for protection. On my first trip with this case, I put my G3 and Canon case into a second, much larger, case because I wanted something to pad my camera).
· Since the case has two parts, when I take pictures, I must find someplace to put the top of the case (that is actually a bigger nuisance than it sounds. Most camera cases can be over your shoulder or on your belt when you are taking pictures—not this one. There is a piece of leather that somebody needs to hold).
· Taking the top off of the base of the case takes considerably longer than taking the camera out of a slightly larger, more well-padded case (after taking pictures, putting the case back together even more annoying).
· Since the top of the case is connected to the base with two snaps and a rather large piece of velcro (1 inch by 2 inches), it is rather noisy to take off (the mood of several quiet moments have been spoiled by this case).
· The case does not protect the camera from moisture or even a dust storm (there are cracks on every side of the camera).
· One of the snaps on the case is situated in such a way that it can EASILY scratch the camera’s lenses (and the rest of the front of the camera as well).
· No accessories will fit on the camera with the case (such as other lenses or an external flash).
· Since the case screws into the mount for a tripod, using this case and a tripod are two mutually exclusive accessories.
· There is no pouch or pocket to store anything (even a small compact flash card).
· Because of its design, the camera will not sit flat on surfaces such as a table or the ground (there is a knob which screws the case to the camera’s tripod mount).
· I have heard it said that the base of the case makes a good grip for the camera, but I find the grip awkward and uncomfortable.
· Finally, cosmetically, I personally, find this case quite unattractive (friends actually started laughing at my case when I first pulled it out).
My opinion is that this case is a complete waste (and it is currently collecting dust in my closet). If you are considering buying this case, I suggest asking yourself, “What do I want a camera case to do?” Cases have the ability to do many things: protect your camera; make the camera easier to carry; help in carrying accessories; even providing an element of style. I have found that this case does none of that.
