This guy had those for sale a week or so ago too but they were broken out into separate auctions. If you search under his completed auctions (I think you have to log on to do that) you'll see them. He was listing the compressors at $6K with a picture of 4 units. If you read the text, it only there stated the price was for one unit. Scam? dunno but he has zero feedback. If someone has the 60K to buy this lot, they also have the money to drive/fly out there to pick it up before paying.
Pretty rare stuff, would be nice...
