I guess I was more asking whether or not it's a good idea to buy used rotors, and Matt's answer was a pretty good one. Anyways I've found a set of 4 drilled and slotted rotors for $157 with free shipping. Had to go online because every local place is cracked out of their effing mind, charging $40+ for a single, regular rotor.

Do these look pretty legit?
