I'm pretty new here, so hello!
Thought I'd share my recent find...
I just recently started getting back into photography after an absence of about 7 years, and it was strictly 35mm back then with a Rebel G. I picked up a new G15 a couple months back (which I love) that really helped me jump back in quickly.
Despite the great quality of the G15, I'd been getting the urge for a DSLR so that I could utilize some of my old lenses, and do some wildlife photography. But, my cash had gone to the G15 and a new G&L guitar recently, so my wife couldn't justify it.
I decided to start searching craigslist and ebay for some older mid to pro-level DSLR's (I wanted a metal body and the physical utility controls that a Rebel won't give you), and ended up finding a 10d listed as "repairable" on ebay for $45. The 'repairable' status was due to a non functioning 'zoom out' button when reviewing images on the back panel, and a small portion of the aperture reading on the top panel LCD not showing; both are complete non-issues for me. It's otherwise in good shape.
I was pretty concerned with the 6.3 megapixel count in terms of image quality and detail...but after using the camera it's surprisingly not a problem. I can get just as much detail as my G15, I'm assuming because of the larger sensor (though the G15 colors are much better, pre-processing.) The images have a pretty 'soft' look before I sharpen, but its easily fixed.
AF is also surprisingly fast and accurate.
Shutter lag exceeds what I'd like, but I'm not going to complain for $45.
I'm sure I'll end up upgrading to a newer d series at some point, but for now, I'm impressed at how well Canon had things sorted out 10 years ago.
