Sata to USB Adapter?

[LiNuX]

I wanted to know if any one knows where I can get an Adapter that converts the Sata port from a LAPTOP Hard Drive into USB so I can plug it into my pc.

I found a few places that sell for around $30 and i dont feel like spending that much if I can get it cheaper and I already tried eBay, can't find the one I need.

Help appreciated, just have to fix my lenovo laptop hard drive, it got corrupted somehow and i can't enter bios - laptop was given to me by my college so I don't want to reinstall the cmos battery cuz they are watching
