I have a Nikon Cool Pix 7500 and my husband has a Kodak Easy Share Z740; both are great.

It depends on your budget. There are many great choices. First question, DSLR or a point and shoot? Second, what is your budget?

Personally, I'd love to have a leaf data back with a medium format camera -- but then again that is like $20k plus the body plus the lens.
