I agree with Hakan that local support is the best. What your local shop supports is usually the best choice. 

I have used quite a few various brands of might welders. Really you can't go wrong with a miller Hobart or a lincoln welder. Even a good used might welder would be fine.  If your looking at a new welder the 210 miller is an awesome unit since it can be switched from 110 to 220. There's another brand of welder that my welding shop sells and they have great reviews on it from welders that decided to get it instead of a miller 210. It's every bit as good as a miller it just doesn't have the auto set feature. Autoset is suppose to automatically adjust your wire speed when you adjust you knob for the thickness that your going to be welding. Really you can't go wrong with any of the big brand welders. I would suggest getting gas for your welder. It makes for a cleaner weld.  C25 gas is what most people tend to use when might welding. I wouldn't bother going to prax air and leasing a bottle. You will get a better deal either looking on Craigslist or local add for a used bottle or buying a new bottle from your welding supply. For old cars and new cars most people tend to use s7 electrode wire.  It makes for a better weld when there's slight contamination on the surface and if I remember correctly, it works better than s6 for overhead welding.  ( I could have mixed the two up. )

Looks like a pretty good setup for a reasonable price.

Never used this particular  machine butt....I've done some mighty pretty work with an Alum. mig gun like that(with the spool). Now this was on heavy Alum.......not sure if this gun can be cut down low enough to weld thin(er) Alum.
