I have personaly bought a HP 8450 from HP's close out page. My main reason for doing this was printing Black&White on Matte and Ilford Classic Pearl papers. I printed the target prints for Cathy's proflies and sent them to her and got the profiles sent back to me. So I printed a few good pictures I took, without modifications to see how close to (perceived) reality the prints would come out. From what I see, I'll keep this printer for as long as it will work. Colors are great and B&W are ... incredible. I also have been using the 102 photo gray cartridge instead of the 100. Double ink quantity for 25% more in price. My first printer was a Epson 720, then an 820 (I think...) then 2 Canon i960's. On all those printers, in a quest to save money, I bought 3rd party inks and always ended up with clogging or unstable colors. I will stick to the more expensive original HP cartridges because I now make quality and consistency my#1 priorities. If someone asks me to just print a bunch of 4X6's for something they want, I'll download the pics to Costco and pick'em up the next day for less than 50¢ a print.
The 8450 is slow, no mistake about that. But right now, my prints are as good as they can get, as good or better than any pro lab I know.
If you need to print a lot of photos, the 8450 will drive you crazy waiting for those prints to come out.
I saw someone post in this forum who paid something like $59 US for the 8450. At that price, I would buy a bunch just to get the cartridges!!!
Most people in the photo club I participate in don't print at home. They all go to pro-labs. They have a hard time believing I get prints like this at home. Nowadays, most printers can deliver, if you spend enough time to get everything right. My smartest move (doesn't mean I'm smart...) was to get Cathy's profiles for the papers I use most. I think it's money well spent if you need (want) color accuracy.
Again, if you are going to do Black and White prints, the 8450 or it's big brother the 8750 (13"X19"), are probably the best way to go.
