New to digital cameras and am in the process of purchasing one at this moment. Need to know what accessories are not optional ie 1. *Memory Card, what type and ball park cost so I don't get ripped off. I would like to have 1or 2 , 1GB cards. Do not know what size or anything. 2. I know I will need a memory card reader. Be advised I only have PIII 600 mhz, PC100, windows 98se, plus a power mac G4, 1.67ghz, 15.2", 512mb, rev5 that I am a newbie to. Thank you
