It's not a problem. I shoot the D700, with medium jpgs for rapid use with the newspaper I shoot for -- they run 3 mb or so -- and RAW 14 bt for my keepers. On an 8GB card that's room for 250 shots. I carry 8 of those cards. I could use larger capacity cards, but I don't like all my eggs in one basket. I figure if I survived with 36 hots on film, I cn squeeze by with 250 on an 8gb card. Buy the camera that suits you best -- price, etc.
