Link-Arc Welders

[ntsqd]

I have the option of buying one of these welders that was purchased very close to when they first became available. It's obviously been used, but it's mounted on a desert chase/support truck that became a mobile welding truck with the addition of a flatbed & 'real' welder. So it's mostly served as an alternator for the truck.
I'm trying to establish what a fair price for it would be. I know what they cost new. A search turned up a bunch of unrelated threads. Any help would be appreciated.
TIA
