I bought one for my shop a few years ago that is in use almost daily. No issues to date. The rest of our small field machines are Miller Maxstar 150's. The Thermal Arc work's great for the money, we mostly use it for tig stainless and it has been a good machine with a decent arc.
Two years ago the thermal arc was running a special around $900 IIRC for the complete setup which was a great value. Compared to $1350 for the Miller Maxstar machine. The mig feature is decent for what it is, it does have short leads. Usually I buy our machines bare and outfit them with 20' tig torches, ground leads and foot pedals for ease of use when working on or building larger equipment.
The only downfall when using it in the field is it requires 240 volt single phase power instead of 110v like the Maxstar machines. So your limited to available power when using it. Home or shop use is obviously no problem.
