Being the odd man out, I paid 1300 for my ugly black USSC 6039 over 20 years ago and it runs just fine. In fact it produces just as much heat (maybe more) than when it was new because I tweaked it a bit. I've never replaced anything on it in 20+ years but a couple stirrer rods because the heat of combustion tends to oxidize them away. Original everything from convection fan to combustion fan.
Needs a cabinet paint job this summer because the finish is getting thin but other than that, no issues.
I bought for it's multi fuel capability. I mostly burn corn or a corn pellet mix 3 parts field corn to 1 part pellets of any type. My prerequisite on pellets is find the best price and buy them. I don't care, hardwood, softwood or balsa wood. Makes no difference. Only reason I run pellets is it mitigates the clinker issue when burning corn.
4 ton a year average x 20+ years is a helluva lot of tons, anyway you cut it and no replacement components ever, but I do maintain the unit carefully and keep it and the venting clean all the time.
The key to good, reliable operation is constant and ongoing maintenance and cleaning the fly as from not only the stove itself, but the venting as well.
Very happy with my $1300 buck investment. She's paid for herself many times over in fuel cost savings.
Would I buy a Harman, no way. Not spending mega bucks for a pretty face, especially a pretty face with limited fuel capability. it's the limited fuel capability that eliminates many units from my consideration plus my unit is 100% end user programmable (via the control board algorithms) to custom tailor all the operating parameters for any biomass, pelletized fuel). Most units today cannot achieve that level of user defined operation.
I can roast ANY biomass in mine and I have. Wood pellets, cherry pits, field corn, pelletized wheat straw, pelletized corn stover and even pelletized DDG, though my main source of fuel is and always will be Midwestern dent field corn at my 75-25 ratio though I can run 100% corn if I want to (with the clinker issue of course).
Might be a manual light unit (no automatic ignition) but that eliminates one consumable part and it only takes about 3 minutes from a stone cold unit to heat with a manual light. Toss in a hand full of pellets, ad a touch of gelled firestarter, a match, close the door, hit the on button and in 3 minutes it cooking along. Extremely easy and no consumable electric ignition cal rod to replace,
I'd say for 1300 bucks it's a helluva deal so long as you can do without the fru-fru that Harman's come with. I know I'd rather spend the difference between a Harman and what I have on something I enloy, not a pretty face unit.
It's for heat, not for show....
