I can get 1 with the same specs as 1 staright from Hobart for $400 BRAND NEW WITH THE 5/3/1 warratany , sohow much do y`all think it`ll cost me to get everthing to tig with it will coast ;80cu. clinder,regaltor(flowmeter),thing that goes to the stinger and to tig rig& i think to the cylinder I`am not sure,

Thank y`all ,Chris
