If you don't need to do heavy welding with the tig, take a look at the 200DX. AC / DC, pulse, foot pedal and hand switch standard, pretty nice little machine. The price is right and it uses very little current. I can run mine with 100+ ft of 10 ga extension off of my 30 amp dryer circuit. Cord never even gets warm.

Any day on a motorcycle like this that ends just needing parts and labor is a good day.
