Criteria

Price range- $250 preferably but 475 absolute max
Have no problem buying used if I have too but must be in good shape
uses- Exhaust, brush guards, bracketry, light work
Must plug in household wall outlet
will probably use 1-3 times a month maximum

I would love something capable of light chassis and suspension work but know that my budget limits me a lot. I will never build a frame from scratch or cut up a frame so I don't need something that radical.

Any suggestions? Thanks
