I have so many questions. I have 1 Gig that I bought when I bought my camera but the more I think about it the more I think 8 day's in the world never been that's like 2 roll's of film a day so not going to be enough. So I think I will be looking at more on Ebay. Does any one have any suggestions or warnings before I start bidding? One other question cause I don't no much about the digital world,a trusted friend want's to barrow the card I have wile he visits the world I know I formatted my card when I got it but is it interchangeable like that. I don't want to risk damaging the card I all ready have. Thank's
