I am looking at buying a used pellet stove and it would be my first one so I don't know much about them. It's a St. Croix York insert. He said he used it for two seasons. I took a look at it and it was manufactured in April of 2009.it comes with all the piping as well. He was asking 1500 but said he would come down to 1300. Is this a good deal? Help.
