Anyone recommend a cheap external optical drive for cMBP?

I don't plan on using it very often so it doesn't have to be fast or anything. Just reliable and not expensive.

EDIT:

Sorry, I meant to ask if there's a certain one you recommend.

I have a Samaung one, seems to work fine and is just bus powered.

Similar to the one I have http://www.amazon.com/gp/aw/d/B005KQ0S8S/ref=mp_s_a_1?pi=75x75&qid=1346640032&sr=8-1
