I know I'm flogging the ground where a dead horse used to be, so here's my last question about pedals. I'm just about to get another pair of the basic Shimano 520s for the singlespeed. But I happened across these pedals, the Wellgo WPD-823. I found them online for a super cheap price (less than $20 for the pair). Of course, a bargain for a P.O.S. is no bargain. Anybody try these?
