He wants "the cheapest" thing he can find. That is 3-4 times the price of "the cheapest". For just around $5 you can get a small plastic adapter that lets you connect a laptop IDE drive to a desktop IDE cord, using a Molex connector to get the power for the drive. Theoretically, you could use it to permanently use the laptop drive in the desktop, or you can use it for quick fixes by swapping it in.

THIS is what you need. Dirt cheap, reusable but simple, and reliable. It's not USB, it's just IDE. However, you save a lot of money and it works just as well. The minor downside is you have to temporarily unplug your desktop's hard drive if it is IDE, but that's really no big deal if you're just recovering. You can always boot from a Linux LiveCD to recover files.
