I was asking around for the same thing a few months back, with no luck. Then somebody put one on ebay on a buy it now for $79 and I snagged it. The B side label was off center, the center hole had damage, and the A side has lots of groove wear. I don't care. I have one now. Hope you can find a similar deal!!
