Just some advice: don't buy any parts with bearings in used condition! Especially an MTB part (with non-replaceable cartridge bearings), they can get quite a bit of abuse. One dooshbag in his e-bay ad described his clipless pedals as still having ultra-smooth bearings. He had a very good rating, everything else was fine. I bought them and it turned out the bearings were worse than the ones I was replacing them with! The shipping too was way over priced. $10.00 to throw them in a cardboard bag. All other transactions worked out well though.
