That's pretty expensive for a socket. It seemed to me the socket that
whoever it was turned up the last time we had discussions about admedium
bases was more in the range of $13. You should do a search of the
archives for admedium socket and see if that link turns up. I think it
was Colin Grimes who was looking for one, but I don't remember which
group member found the socket that time. But someone did turn one up and
I'm sure it wasn't $68.
