Bidding on rare desirable parts on eBay and having everybody publicly posting and advertising about it on the internet on bulletin boards is one natural way to drive the price up when somebody else suddenly wants the same part, or even worse, invite shill-bidding if an unscrupulous seller gets wind of it. I'm certainly not accusing anybody here of such a thing, but maybe a little discretion may be in order. We'd be helping Russ more if we simply use PM's if you got a good lead.
