I'm having a hard time of keeping a TIG on my want list. It seems to be on my need list a lot latley.

If my car sells I will be buying one now if not its time to save up for one.
I will be doing mild steel, stainless, and a little bit of aluminum. I'm looking at the Dynasty 200DX but at at 3500.00 ready to use I am also thinking about the Syncrowave 200 because 2500.00 or less new and they pop up pretty regular used for a good bit less. So what should I lean to? Thanks in advance for any advice.
