Further to before, I've got a quote from USBpen.co.uk for 350 x 2GB USB drives with the logo on (may have to be the orange & black version):



Comes in at about €2,000/£1,800.

It's a plain style, but since it doesn't have much in the way of a bulky case, it's small and fits in even the most recessed USB slot. I've got a 1GB from work, and it's the best pen drive style I've seen.
