I just picked up three Sandisk Extreme IV cards from Beach Camera for a total of $240. There's a super sweet rebate deal going on, where if you buy three, you can get $160 off.. so each card came out to just $26.66!!! Information on the rebate can be found here: http://188.8.131.52/rebates/SandiskQ3VisaRebateExp092808.pdf Rebate works at almost every major camera store. Offer doesn't expire until September. I looked through all the possibilities, and the 4GB Extreme IV gives the most bang for the buck. It's really hard to resist at these prices. Enjoy! Anthony.
