I purchased a Hobart Handler 187 two weeks ago. Prices for a 20 cubic foot mixed gas tank locally ranged from $139 to $169. I got a 40 cubic foot tank on EBay for $65 shipping was another $25. You just take your tank to a gas company, and they swap you for a full one. It cost me $28 for a full tank. The counter guy said that it should be good for about 3 3/4 hours of welding. That is with a flow rate of 17 cuft. an hour.
