Well, i have heard a few schools of thought on this subject from photographers about cards. One of the guys I shoot surf contests with actually has several 512 cards he uses. His reasons are 1)if a card goes bad there are less photos you lose & 2)the camera process images faster. I have found that the 2nd really holds true. I have a few 512 cards and 2 1 gig cards and I like using the smaller ones better. Especially when I'm shooting portraits and contests. All of my cards are sandisk except for one lexar gig card.

Just my $.02, hope it helps.
