Go for quality of lens rather than number of pixels first. You can print 5 x 7's from 1.3 that don't look too bad but to get near conventional photo quality at that size you really need 3 megapixels, and that's only 'near'. If you're printing you're own the quality of the printer and paper makes as much difference. For web work a good quality 1 megapixel is more than adequate.

www.epinions.com has good reviews (and a few dodgy ones like most sites).
