Unfortunately, my old Sigma DP2 has some dust on the sensor that I can't remove. As I am very happy with the image quality, I am instead considering buying a Sigma SD14 or SD15. Where can I find such a camera, is there anything I should be aware of, what is a reasonable price, and which lens would you recommend?
I would buy these:

The reasons I would pick the SD15 vs the SD14 are as follows:
The SD15 has a bigger, better rear screen, which is essential when reviewing your photos to check if focus on your shot was perfect.
The SD15 operates more quickly than the SD14.
The SD15 records in RAW+JPG mode, which the SD14 does not. I find that I use out-of-camera jpegs a lot, and only go to the raw files on occasion, when necessary. Therefore it is essential to have jpegs, and having to pull the jpegs out of the raw files is a pain/hassle.
The SD15 operates more quickly than the SD14, and the SD14 operates very slowly, clearing the buffer slowly, reviewing photos slowly, etc. That is a big deal to me. You might not care about having to wait around, but I don't like to wait. Still, I dealt with my SD14 for years, and still loved that camera.
The SD15 has a massive raw shooting buffer, which can make or break you (about three times the capacity of the SD14 raw buffer, which is bout six shots), when you're shooting something like models or wildlife. For example, you might shoot a series of photos, and then run into the camera's buffer, and be unable to shoot for a while, while the camera clears the buffer. While you're waiting a shot might present itself, but you can't take it, because you're waiting for your slow camera to clear the buffer. The SD15 has the advantage in this instance.
Things to remember:
The SD14 and SD15 are not weather sealed, like the SD1.
The SD14 and SD15 make 4.7 MP images (though they are equivalent to the images my 12 MP full-frame Canon 5D could make). I had a Canon 5D first, and did not miss it when I was shooting with my SD14. In fact, the SD14 offered more dynamic range than my Canon 5D, so I actually liked the image quality from my Sigma better. I also had a 10 MP Sony and a 12 MP Nikon before I got the Sigma SD14.
My preference today is the SD Quattro H. It is the best Sigma camera I have ever owned.
I also like this lens, which offers more reach:
I had one of those lenses for my Canon 20 D, which was the first SDLR that I ever owned. That lens was great, though it doesn't have OS, which is why I would get the 17-70 instead. It is nice to have the extra reach though. I always wished Sigma would make a really great replacement for their 24-135, which would have OS, but they never did. If they had, I would have bought it. I think an 18-135 or 24-135 would be a perfect all-around zoom lens. The 18-125 on APS-C is a really great range, and doesn't suffer from the image quality limitations that the newer 18-200 OS suffers from, unless I'm mistaken.
