I myself will be getting a 210 EXT for it's capabilities, but redbeard's comments about TIG hating rust is very worth dwelling on. I've done a lot of rust repair on a musclecar project I'm building and a MIG is really what you want for rust repairs. I personally want a TIG now because I've moved on from the rust repairs to a lot of clean new metal fabrication, suspension parts/mounts, etc. where the heat control and AC for aluminum will be needed, but for general auto body repairs if I had a choice of only one machine I'd have to go the MIG if any of the metal is rusty or corroded. Just my thoughts......or you can get both!!!!
