I've used the Riley, Cylinder, propane and a home made job over the years. I was lucky enough to wake up to the sound of hissing and a mjor headache with the propane stove. Somehow the flame went out and was pumping propane into the tent all night. Whether it was a defective unit, or operator error, I wasn't willing to try a second round with a near death heater. The riley was fair, but was always a mid night re-stoke to keep the fire going. Especially after it started to deteriorate and warp. It always drew too much air and burned too fast, plus alot of smoke as was mentioned earlier. I am envious of the guy who had great luck with his. THat is what I was expecting when I bought it. The home made one did great, but was built from an old waterheater or propane tank as I recall. It was a friends fathers brainstorm. The only drawback was it weighed more than a small deer and had to be assembled everytime. The cylinder has been trouble free and great since day one over the past 7 years. If you control the air flow, it keeps me warm all night and there are coals ready to just add a log and open the damper in the morning to get it roaring.
Sorry, I haven't heard or seen anything about a top loading stove.
