am I missing something with some of these prices?

Only thing you are missing is that this is a "part dealer" who is making plans for his retirement off these prices.

They pop up every so often on eBay unfortunately.

This is the dark side of the law of supply and demand.

Some people will be crazy or lazy enough to buy from him - I can't even if he has a part I need.

Pretty typical ebay stuff if you ask me.

Numerous errors and omissions. I don't think they are intentional, it is buyer beware.

Caveat Emptor!
