The Everlast 210EXT gets good reviews and has nearly all the features of the Miller Dynasty 200DX for $1500-1800. As Greg mentioned it probably would be fine for home shop use/duty cycle. I've considered this strongly. They used to do a 5-year warranty if bought direct from them and not through a reseller. They negotiate pricing if you call them. A lot of the online welding supply houses now carry the conversion fittings and items to easily run any of the major torches etc. like CK and others. Again I don't have a TIG just what I've researched.
I see several transformer Sychrowaves or Lincoln Powertigs on Craig's here in Denver area almost weekly. I'll go for a digital unit, but the transformers can be bought very reasonable used and as Blake said, last forever.
