Any good guides for buying on this secondhand market? I'd love to pick up some older decommissioned hardware but it's hard to find and harder to trust

I'm not in the market myself; a number of friends buy them on eBay, but I don't know how to differentiate between good and bunk. I would assume that if they're selling 50 of them, though, that it's a good guess.

Still, I think it's always something of a gamble. Maybe look for reputable dealers on there.
