I'll just add; make sure you match the type, bipolar or unipolar, to the driver (board) as well. Some unipolar drivers will run a bipolar - some not, and vice versa.
Balsaman's recommendation a while back, was if he was to do it again he'd go bipolar. But when you're shopping on ebay - sometimes its buy what is available!
