i have a quadra fire sante fe. good unit, and other than a power surge frying the electronic box, it has been trouble free. pellet stoves need to be cleaned, sometimes the burn pot has to be emptied once a day. this is directly related to the quality of the pellets burned. my stove will go for a weekend sometimes before it needs to be emptied. for me it has saved me a bunch of money, and has paid for itself many times over. i still will be installing a wood/coal boiler this winter, because i do have to run the boiler when temps get below freezing for extended periods. pellet stoves in no way replace a central heater, i think thats what some people have fallen for, or they purchased a stove that is way too small for thier needs. its pretty much along the lines of any other freestanding stove in that aspect.....its not a central heater. i have mine figured out to the degree when i should turn it off and turn the boiler on. i plan on using my pellet stove for late fall and early spring heating, the boiler will pretty much cover the coldest months. most quadra fire stoves will burn 50/50 pellets/corn, however i did burn pretty much straight corn in mine for a while. lighting corn is kinda hard, thats why they say 50/50. i think we all know any stove from the big box store, wont compare with a quad, harman, vermont casting.....etc.
