encrypted USB drive recommendations

["Youngquist, Jason R." <jryoungquist () CCIS EDU>]

Does anyone have any recommendations for cost effective encrypted USB drives?

I know the Ironkey USB drive is one of the defacto secure USB drives out there, but we were looking for some lower cost 
solutions that we might recommend to faculty/staff/students.

Key features:
--reasonable price
--easy to use
--Windows and Mac compatible.
--USB drive must only have an encrypted partition (some USB drives have a non-encrypted and encrypted partition)
--size really doesn't matter - 2-4gigs should be fine


Thanks.
