I have a quadrafire 4300 we bought back around 2009. At the time the goverment had I believe a 40 % rebate on epa approved stoves. Mine listed $2400 and paid $1600. Plus quadrafire gave a $150 coupon for a stihl saw. Dad has a blaze king with the catylic convertor. Probably got it in 1985. GREAT stove. Kind of wish I had went with a blaze king. But the 4300 does a good job.
