I'd like to make some promo items for my business, but I've been a little shocked at how expensive it is. The last I checked, to put my logo on something like 25 2GB flash drives costs $10/drive. That seems really high to me.

I'm sure the equipment to do this is really expensive, but how expensive? If I plan to do lots of these drives it might be worth it in the long run. Isn't it just some sort of thermal printing process?

I've been trying to research this but I haven't had much luck...
