toward the bottom of the page.
I just "sold" it for $200 on ebay, then non-paying bidder and big hassles with all that. Did you know ebay no longer allows sellers to leave negative feedback for non-paying bidders? Incredible. Anyway, I am totally done with ebay and am now doing what I should have done in the first place; selling it to the good folks at VAF, rather than trying to wring every dollar out of the deal in an auction.
Selling for $150 plus a $10 donation to VAF, or a total of $160. Includes priority USA shipping. If you want it, I will also throw in the bad vacuum pump core for free.
