A bit late to the party, but I've been REALLY happy with a Lexar P20; I've got the 128gb but they make 32gb/64gb as well. Really annoyingly pricy (and worse by about $10 back around Christmas when I got it) but really, really fast -- 100MBytes/sec+ write speeds on larger files, and often 200MB+ reads.

Pretty solid metal case, too.

The CZ80 sounds like it's in the same speed class, and it's a bit cheaper for the 64GB, so it might be the better option. For ~$31, I'm tempted to pick one up myself.
