It is hard to find the good stuff, but in my area I have found coal that is as low as a 7 to 8 ash (7 to 8 lbs per 100 lbs of coal). Of course I have also purchased some that was a 25 ash and that is from suppliers that take the old piles of coal and mix it in with the good stuff.
Best bet is to talk to folks who run stokers and buy from dealers in your area to find out who has the good stuff.
As far as stove reliability I have seen many 10 year old Harman Magnums still working. They are heavy and built like a brick S#$@ house. Then again I have also seen lots of the old style Alaska Triburner stokers and they seem to keep on running with just a little work and are half the weight of the Harman.
My advice is to buy from the dealer who has the best service. And since Liesure line is the only one who has the guts to come on this forum and represent their product (thanks Jerry), I would say they are probably the best in that department.
