can anyone recommend a good one upto £100?
3Mpixel / rechargable battery / 3x zoom / small
and whats the best mem card type to go for?
Erm, one that works with the camera you eventually buy 
If you’re going to take everything at 3Mp (and you probably will) a 512 card is a good size imo.
Ask the question of our friends over at digi-darkroom.com. Loads of opinions in there.
