The web site does the standard request a quote which is lame, but a few more lines down on the google search turned up this posting which gave me a ballpark figure:
Pro-Fusion Dual-Arc 80 Micro-TIG/Plasma System. Our R&D project has been completed. Used less than 50 hours. Available for $10,500 (shipping & insurance additional).Guess I better stick with the low-budget stuff from Lincoln and Miller.
