Do yourself a favor, plan on spending around $140 and get one with a little regulator and a storage tank, You fill the tank and then its portable and has quite a bit of uses like winter-proofing boats and RVs. Mines labeled "Triple-Play" and has the Ingersoll-Rand name as manufacturer. Tank holds about 110 PSI, If you're cheap, someone sells a kit to convert that old propane tank out in your shed into a storage tank... just be carefull!!
