I have a Canon digital Rebel XTI 10.1 and I love it.
It takes amazingly clear, crisp photos, it's fairly simple to use, yet has lots of extras and option to really get some professional looking shots.
Best of all, I can really enlarge the photos with little to no loss of quality. I have several lenses that fit it, because almost all Canon lenses fit, not just digital specific ones. I have a standard 35-70 mm, a panoramic 26-80 mm, and 100-300 zoom. I also just invested in a set of macro lenses. Not the big expensive ones mind you, these are just little things that look like filter you screw onto the front of your lens, and they work great.
Here are a few examples:
Taken with my 26-80 mm and a 4X macro.
