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?

Black Friday is the day when all the flu vacinations given to millions of people are activated, turning generally frugal individuals into all consuming, shopping whores.
 
Really though, its the Friday after Indian Killing celebration day.  Stores mark stuff down big time....there are many reasons why they do this.  In summary, "yay capitalism"
