Any superior brand in compact flash cards? I know Lexar or Scandisk are the biggies. My camera shop only carries Promaster. Are they all the same or is there a difference? Any superior brand in compact flash card readers? From what I can figure out it's a copy/paste from the card to your hard-drive. What are your feelings on the size of the card. Most cards larger than 256 or 512 max mb kinda scare me because if there is a catastrophic failure lots of work could be lost. What are your feelings or thoughts on these matters?
