[font color=\'#000000\']Lexar's seem to be preferred over on the DPReview forums. Anything much above 12X won't speed up the camera much.
Sandisks seemed to be OK, but my memory is that the 80X Sandisks weren't any better than the 40X ones.
I have had good experience with 512Mb 12X Lexars, Viking. Slow with a 512Mb Viking (older card) and Transcend 25X, I had really good luck with some 2 year old 256Mb Kingston cards, but who knows how they compare to what they are selling now?[/font]
