The model is a Mr. Heater. Fred Meyers $40.00.
buy a small tank and rig up a hose yourself with gas hose at nappa. The fittings you can get at sporting goods stores and nappa. I have a set up like the one you are talking about, works great.
I also use a propane tank hose and fitting to a propane cook top and coleman propane lights for elk camp. I wouldn't know what to do without it.
