thanks Sebc
I agree smaller is better then if you lose or corrupt one you don't lose everything.
Found this data out there re capacity:

Based on this a couple 4gb cards should be fine.
I am going with the d5000 kit with the 300mm lens. I am contemplating adding the 18-105mm at a bump of about $300. I think it would give me the most flexibility. The 300 is a beast but even if the quality at the very end is not that great I don't have to go all the way or I would not have gotten the shot anyways. The short kit lens really does feel cheap but the guy said it is much better than they have been in the past and take pretty good shots.
I am also thinking of this bag:

Any thoughts?
