SATA to USB drive reader?

Recently i found my Western Digital Elements drive for time machine not mounting, curious as to what happened to it, i unplugged it and plugged it back in, the light went on then faded quickly off. I have since taken it apart to rescue my external hard drive from it, but now to get the data I have on it off, i need a SATA to USB cable (note, not ESATA, just SATA) and i was curious as to if anyone knows of any place to get one. Also any recommendations on a good Time Machine drive (preferably cheap and in the 500GB+ range).
