well it seem im going to be needing a camera so im trying to look for a good one under 100 if possible. And i hope to take some good picture not crap ones.
My 1.3Mp camera takes pictures just as good as an average 35mm camera... I would have to believe that 3Mp should suit you just fine unless you need the highest quality possible.
(I love mine though... one of the only ones with 1.3Mp and a nice sized LCD screen... cost $400 when digicams were much newer, bought it off a friend for like $40 a while ago )
