WTB: water-cooled Tig Welder, pref Miller/Lincoln

We are looking for a Miller or Lincoln Tig Welder that's water cooled. Preferably something equivalent to the Miller 250 DX/LX series or better. We're looking to keep our costs down on starting up our auto performance business.

If you know of any person or company that would have one available for a reasonable price (preferably used), let us know.

Thanks!

Cynthia
