I've had two and I loved them. I could use simple kerosene for both the stove and the heater I had. They are preheated with a bit of alcohol, then they light up and the BTU's are very high. I didn't have any problems with clogging or soot.
I should point out that they both came with the boat. They are quite expensive new these days.
I'd like to know where you might be purchasing
yours from, as I would also like to get another one.
