Im buying a Sony P50 next week. Its a 2.1mpx and I was wondering if a 64mb card would be sufficient? Or should I step right up to the 128mb? Do you guys find that once you know you have the abillty to take over 100 pics, instead of a roll of 24....you just get shutter happpy and click away? The 64mb card is $90 CND and the 128 is $150 CND...cheaper than buying 2 64mb cards down the road.....decisions decisions.
