should i get......

i was at babbages today and they had an original xbox controller(the one with the green jewel) for 30 bucks because it was used. the green jewel however still had the plastic to keep dust of on it. i was wondering if any of u had bought a used controller before??? did u have any problems??? should i get this one???

i would...thats going to be worth something in a few years...i'd do it, maybe in the future it'll sell for like 100 or so:D
