You don't need a fast one or a large one. There is only 16.7MP RAW + JPG as the largest size to record, no video. Buffer speed is not great, so any Class 6 or 10 SD will be fine. I don't see any reason to go larger than 16MB, and that worked fine in mine when I had it. Don't know why your 32GB didn't work -- maybe a limit I am not aware of. More likely the type of card (did you get a "7"?). For CF and SD, I've had good luck with Transcend and Kingston, without spending for more expensive Sandisk or Lexar cards. I've not had one fail yet.
