I have a pair of the Syzr pedals, stainless steel spindle version, from Speedplay, maybe 100 hours of use. Pedals in perfect condition, the cleats have a tiny bit of scuffing, as you might expect, though they're metal and are almost impossible to wear out.
I bought them because I needed more float than I could get from SPD or EggBeater pedals. Unfortunately, I need more than the 10 degrees they offer, so I'm switching to Frogs. Sucks having a really bad knee.
They retail for $199, asking $90, shipping included in CONUS.
