Well if they weren't available I wouldn't be able to afford an AC/CD tig.
Six grand for a "real" machine for home hobby jobs just isn't feasible for me.
I recently bought a 200 amp ac/dc Tig from Token Tools here in Australia, this process took me 6 years to commit to spending the money, talking to Pete from Token Tools and many other shops.
I couldn't find any negative comments or posts on either Token Tools, their after sales service or their welders other than the Chinese vs real welders debate.
I did a TIG course 20 years ago and successfully splashed molten aluminum consistently over my feet, with this 200 amp TIG I can actually weld aluminum, not pretty yet but better than splashing my feet.
The fact of the Chinese vs the rest, is the Chinese have flooded the worlds university's with their students, they buy the best machining technology from the west, they are listening to the fact the world wants quality, not junk and their products are improving.
Jody's test on the Everlast TIG says a lot, if it can impress a long time professional welder, perhaps the chinese are starting to do something right.
Having said all that you still need to do your homework and buy a reputable brand from a reputable dealer.
