An interesting offer

I was at the local HF store today, and in passing asked the manager about the little 130 amp tig welder. Did he have a lot returns? Problems with the units etc? He then said. "I can give you this unit at the last sale price ($179) if you purchase the 2 year extended warranty with it for a total of $213". Sounded like a good deal, but because I am not well educated on tig machines, I declined. Has anybody had experience with this machine? I am just new to o/a gas welding and use my torch for sculpture projects mostly using 3/16 to 1/4 rod. I'd like to weld stainless at some point but am not ready to work with stainless...yet. Also, it has been my experience that buying the best is always cheaper in the long run. However a sweet deal will certainly turn my head. What think? Go back and get it? Mike
