yours is not the first story in which someone's been outbid on a Lisa but gets it later on when the high bidder doesn't pay.
That's how I got mine. Bid £150 for my dead machine but got outbid at the last minute. The guy who won then turned round to the seller and said that he thought he was bidding in dollars instead of pounds (?!?!?!) so second chance offer to me. Drove down to London to collect it and the guy knocked another £10 off. Get it home, give it a check over and hit the power switch...all springs into life (screen just needed adjusting). One very happy TheNeil
