eBay is going to be your best bet unless you luck out and find one in a dumpster or at a garage sale. People who know what they are won't let them go cheap.

$370.00 for a broken pump? Not worth it, not even close.

Tom. I've got a 2 stage pump you can have for £10 plus shipping. (It's HEAVY, so I don't think Royal Mail will move it. Maybe DHL etc?) It could do with some new seals. Generally it's ok after a few minutes running. That said, I've not run it for a few years. PM me if interested. Cheers. Mark.

Cheers Tom.

Probably generic O rings. They seal after a while, but it will spit oil from the exhaust for the first few minutes.
I used to pump a Fusor down with it and evacuuate homemade valves and glowtubes.
No time for such shennanigans these days.
I'm in Sidcup, Kent.
Mark.

EDIT: It's a Speedivac High Vacuum 2 stage pump model 2sc2a in case anyone can help Tom with seals.

I've a couple of addresses for people who supply rebuild kits for Edwards pumps at very good prices. I'll look them up. (I think I've posted details here before somewhere)
