Flash drives: PNY Attache vs. Sandisk Cruzer

Hey, I want to get some opinions here.  There's a couple of Black Friday sales on the Sandisk Cruzer and PNY Attache USB flash drives.  I really would rather get a Lexar JumpDrive Lightning for its on-drive security features, but for the prices that are being offered ($80 for a 2gb USB flash drive?  YA RLY) I think I can suffice.

So does anyone have any recommendations/warnings/cautions about either?  This thing is going to be carried everywhere on my keychain.  What I want to do is get some sort of flash drive security software that password-protects it and works on IBM PC computers. 

Any thoughts?

PNY Attache is a piece of fucking shit.  I had their 512MB version, broke after a week.  The thing is flimsy as hell.  Had some irreplaceable MS paint drawings on there too ;_;
