I've been using the 2GB Extreme III cards for almost a year. Got tired of swapping, so I got a couple of 8GB cards. The 8GB card is just as fast as the 2gb card as far as I can tell. With the rebate, these are not only the best performance for 8GB cards, but the best price for high performance 8GB cards. And the card reader is a bonus.

Good performance in my Nikon D40. Worked seamlessly no problems. I also use for temp data transfer between computers. I bought 2 copies but got the Sandisk rebate for one copy only. Sandisk is arranging rebate for the 2nd. Price with rebate is fantastic. SD card-reader included is a convenient bonus. Adoram rocks.
