TBP, Migo, U3, etc...

I'm thinking of buying a new Kingston flash drive. I am looking forward to:

** Kingston 2GB USB 2.0 DataTraveler II (Part n° KUSBDTII/2GB )
or
** Kingston Data Traveler II Plus - Migo Edition 2GB (Part n° DTII+M/2GB )

Anyone has had any experience with TBP and U3, Migo or secured flash drives?

And with any of these drives?? I'm excited about the secure or encryption features.

Thanks a lot for your help.
Sergio.

PS: And I have to add that John has made a superb job with Portable TB!! Thanks man!
