FWIW, I've also made a number of purchases from buy.com without any problems. I also have three Sandisk products, a CF card, a memory stick, and an SD card. All have performed well over the past year although the SD card is slower than my Lexar SD card. My Sandisk CF and SD cards are 512 mb. I have read of more problems with 1 gb cards in general and Sandisk card in particular but I have to wonder how many of these problems are the fault of the card or the operating system, which just gets more unstable when you're accessing a 1 gb card? Just musings on my part but it seems like I hear of lots of problems with 1 gb and larger cards and much fewer problems with smaller cards.
