Just about all digital cameras will do for what you want. The higher the megapixel, the better. Make sure there's a macro setting for close-ups shots.
I use an el cheapo Kodak Easyshare CD82 (12 megapixel). They cost a whopping $79 at Wally-World.

Here are some shots I've taken. I've been pretty happy with the results....
