I bought one of these decks from a seller on Craigslist for $75. It works fine, but the loading mechanism is faulty -- the metal inner part that sweeps the disc into the playback riser seems to be aligned OK after some finagling with the gears, but the entire riser seems to have a mind of it's own, coming up and down whenever it feels without the drawer being in the correct place. Is there some sort of alignment procedure for this deck? I'm fixing it with the goal of trading it for an MZ-RH1/M200 at some point.
