I have been reading up on various Tig machines and I am leaning toward a Miller Syncrowave, but it is like going into a stereo store- too many options.

I have looked at ESAB 260's Lincoln 355 SqWv, M350Dx, and there are so many other miller machines that do TIG of different sorts. (drag / lift Start / HF start etc.)

I have used a 200 DX to tig together some projects, and I am a bit concerned that a synchowave 180 may be light on current, so I have been looking for a bit bigger machine with HF, foot control, and the capability to weld 3/8 steel and AL.

I am looking to hear what some more experienced tig welders are using.
Anyone willing to share some words of wisdom?
