I don't know that your idea would work bac, as we're not the only ones buying these. There are what, 5000 members at benheck, and 100 here? I konw that a good few thousand at benheck probably don't even post, but still, I think even if we were to try and do this we would not be changing anything, just knocking a few potential bidders from the swarm away.
BUT, Palmer did have a good idea yesterday, to have a Modretro store where the admins/etc. would buy large lots of items, and sell them at minimal profits in the store. Sound like it could work out well, remember the 100 or so zenith screens that one time?
The only other thing I can think of to do really should not be done under any circumstances, and that is this: A group of people decide they want an eBay item or they want to help buyer A get that item cheaply. They all use eBay accounts they can afford to lose. Buyer A puts in a bid for the minimum. Then all the other buyers put in large bids to jack up the price to more than anyone wants to pay. Nearing the end of the auction, they all retract their bids, thus leaving the minimum and not much time left for it to go up. There are flaws though, like if eBay were to deny the bid retractions. After all, you do have to come up with a good reason to retract your bid, and it isn't supposed to happen very often.
That last idea shouldn't be done, IMO, it's cheating!
However, bac's idea seems fair enough, but hard to accomplish IMO.
