So ive been learning how to tig weld in school which has been making me try to figure out how to obtain a Tig Welder for home use and use on my car. The main purposes for it for me will be for the car, i.e sheet metal, roll cage fab, etc. What are some things I should be looking for when considering a tig welder. I know I want one that can run AC for when I start to learn how to weld aluminum. I want something that I wont kick myself for buying once I realize I should have spent a bit more because what I bought can't handle what I need it to do. Any input would be great. I would love to keep the cost as low as possible obviously but cheap and welder are two terms that just dont go together. Any input would be great. Ive been checking out the Dynasty 200 dx and the syncrowave 250 dx from miller.

I would love to hear your input. As it stands now, both of the welders I've been looking at seem to be priced out of my league so if there are any suggestions for a broke college student I would love to hear them!
