Hi, I recently found a Harman XXV on Craigslist and I've been thinking of replacing my wood stove. My question is if the stove is worth it. It's been through 8 seasons and looks like it's been very well maintained. It looks almost brand new. The owner has only done routine maintenance and it seems like he's been very meticulous. In my opinion is in great shape but I have no idea what kind of life span these stoves have. He's asking $1800 with 1 ton of pellets included. Good deal or no?
