Miller 330ABP, low hours, works great $500, this is a single phase only that can run on 200,230,460 volt. For you younger welders the 330 ABP is an AC/DC TIG/ stick machine that has great low end performance( through approx 210 amps) for AC GTAW. DC GTAW is goood through the entire range of the machine. DC SMAW is also a very good performer even with 6010. No torch or cooler is included.
Miller ShopMaster 300, AC/DC/CV, low hours, $550, this is an older Shopmaster 300 from the early 90's single phase only 200,230,460 volt, it does not have balance control that the newer ones have. It does include a Lincoln Hi-Freq unit to do AC/GTAW, DC/GTAW, can also run wire, no feeder included.
Miller CP300 3 PHASE ONLY!!!!! $ 750. This one belonged to a little old lady from Pasadena!@#$%^ just kidding men (and ladies). It does also have very low hours-no kidding. Again for you younger welders this was one kick butt machine in it's day and still is in use in many shops. This one has a Spoolmatic one pound spoolgun for GMAW aluminum and can also run any other wire that requires up to 300 amps. I used it running .062 E71T1 on rollers doing API1104 and never had a repair.
These fine machines are located in southeast Pennsylvania, in the York area.
