I came across a guy selling a harman accentra. He is selling for 800 bucks comes with pipe and oak kit. My question is, is this a good price? The stove was stamped it was made in 2003 so it is fairly older. It has a little rust on it but nothing that cant be sanded and a little bit of paint cant fix. He plugged it in and turned it on the blower works the auger turns. The only problem with it it the plate in the pellet box that drops the pellets is frozen shut. Looks like it is just rusty. So my question is, is it worth the price and with the plate can i just take it apart sand the plate down and free it up so i moves again?
