PJS: I'm also at that point on my panel. I have one decent side and one bad side. I think finding GOOD used ones are almost hopeless.
The new ones are about 80 bucks plus shipping....I saw some in the swap meet but the guy wanted $75 for them. If they were in good shape I'd say OK as they are probably a lot "heavier" weight than the overseas crapp.
Maybe someone who has purchased the aftermarket will chime in here. I'm interested to.
