Lyman aluminum sights - Lyman 66 Receiver "Peep" Sights

I was a sucker and bought 6 aluminum Lyman sights thing that they were as good as the old steel sights. I couldn't have made a bigger mistake. Bump these aluminum sights and they'll have to be replaced. I'd gladly pay three times as much for an older steel set. I've been trying to unload these sights for a fraction of the original cost. I'm sure that the new owners will hate the aluminum sights as much as I!
Pros: can't think of any
Cons: weak, flimsy, can't stand being bumped
