TIG welders?
Any of them operate on 120V outlets?
Having the capacity to weld in AC is what makes the first price jump. Most will weld anything you'd need in fabrication on a car.
Having gone down this road once, I'd recommend you consider buying a AC/DC machine like the Lincoln 185 instead of the cheaper way out with an inverter welder.
youll thank me later) and SMALL!Check ebay- I know John (XL8nss) knows of some good places that have good prices

The Dynasty is an inverter type which is capable of running on 120-460V while weighing 45lbs and having a very small footprint.
Louis might know a thing or two about this one. 
The Thermal Arc is basically the same thing but, runs on 230V only. Weight and size are about the same as the Dynasty which makes them very portable. The Dynasty is a bit more portable because of the voltage hookup.
The Miller Sychrowave is cheaper than both of those but, is also ALOT bigger and heavier, not something you're going to be moving around much. I believe Harlan has one of these so that should speak for it's capabilities.

If you look around the www.brwelder.com site you can find all three. I think the Indiana Oxygen store in the Ebay link I posted above might have slightly better prices. Shipping is free from both brwelder and IO for outta staters which you are for both.

Millers reccommendation for Amperage is 1 amp, per 1 thou of material thickness. Its spot on too.
BTW, some of you might not know this but I was actually a stick/TIG welder for about a year during college. I learned alot back then that has paid off now in fab work
