I use a Canon XTi, which in RAW format also saves a jpg (wish it didn’t wastes space.) My cam is 10.2 mpixel, I can get about 2-400 shots with a 4 gig card usually. I have a 1gig card just in case I go overboard (and I often do.) I do my editing with Roxio Photosuite–totally old-school, but it’s easy to use and suites my needs. More simple editing (gamma, balance, etc) I just use Irfanview. And after filling my hard drive, for less than $100 I got a terabyte backup at Frys electronics. I never delete anything, except the ultimate crap like poorly focused images. Edited images I save in RAW and also JPG.
