Greetings cheaptrinkets,
After searching on the Internet, I found these pen drives. I made sure
that among the first in the list would be the ones closest to your
requirements. I listed as many as I could find:

USB Pen Drive and UK USB Pen Drives – starts from 24.99 UK pounds (the
64 MB I guess) including VAT
http://www.usb-pendrive.co.uk/
- Up to 1 GB only though. Does not say if it has USB 2 compliance. 

PenDrive, USB Flash Disks, Pen Drive

- Though the Jetflashes not strictly pen drives (with the clip), they
certainly have USB 2 compliance and security features.

Based on these choices, I reckon the Jetflash models would be the best
in this list.
