I picked a shorthood up for $300, two engines, original machine but had not run since Eisenhower was a Corporal! A buddy of mine picked up a running machine in good shape around here for a $1000. Have seen a machine on cl the last few weeks for $1500 from a guy down in a place where I know there are several pipeliners living. The one he has got is nothing to look at but supposedly runs and welds. I've seen running machines in the $700-1000 range but may or may not be shorty's. It seems to me shorty's are like the holy grail next to the red face machines. Just the name alone invokes a certain percentage of monetary increase. Don't think I'd be paying $1500 for a machine I have to go out and throw the arm cracking tool on to start though, but maybe if the 200 feet of lead is as new as they say then maybe it would be a trade off.
Then again it all comes down to the guy selling it. Some know it's a good welder, used it at the quarry or something like that and that's it. Other guys, pipeliners, etc., know they are highly sought after, prized pieces of equipment and will put a dollar figure on it to match. It's like anything though, Grandma with the 68' Chevelle in the garage that her son bought new then got shipped off to 'Nam and never returned. She wouldn't know the value of that car to save her life. Now put that car in the hands of a guy who's sole career has been working on, restoring Chevelle's and it's a different story along with two different prices you'll end up paying to aquire the car in the same condition. Just my .02.....
