Office Depot has the EMTECH 32 GB drive on sale for 14.99 however the drive takes almost twice as long to write the files to, and the EMTECH drives are NOT recognized by all computers. Specifically some older Compaq, Dell and Toshiba laptops will NOT boot from the EMTECH drive at all, although those computers will boot from my Kingston, Sansdisk and PNY drives. So be aware, you WILL get what you pay for.
So for now I would only recommend the Kingston, Sansdisk and PNY drives.
If you need to remove the U3 system from a Sansdisk drive the link from Sansdisk to do so is :
