larrynjr, I am brand new here BTW. I researched alot of mig welders and bought a Hobart 187 from Tractor Supply in Oklahoma for around $650. It is a 220v unit with a 30% duty cycle . A Small argon/CO2 bottle will cost around $80 shipped on ebay. Hobart is made by Miller only 25% cheaper. Same warranty.
Hope this helps,
matt
