I've said it elsewhere in another subject thread but I get about 3 times as much burn time with a BBQ tank that costs me less than $20 a refill compared to the biggest acetylene tank I could buy ($65 a refill) and not rent from my local welding supply store. A BBQ tank of propane will last just about forever for a hobbyist.
In fact there is enough propane to build a frame or 2 in those small containers sold for a variety of purposes like torches and portable stoves. The problem with them is that their fittings are not compatible with regulators used in welding. A BBQ tank has the same GCA-510 fittings.
