Econtig bit the dust... it's not offered anymore
If you just want CHEAP TIG machine then look at the Maxstar 150
It won't weld much - but if you're only interested in doing thin gauge materials then something like this is small and compact - inverter - with pulsing but no A/C... so you stick to steel and stainless steels. The move up to an A/C D/C machine is a large jump in price - but then you can weld aluminum - and for me - that's the reason you have a TIG for hot rodding. Lots of aluminum parts in my cars - brackets etc.
