I currently have an old Jensen that is falling apart and is not connected to my flue in any way. I am thinking of buying this stove = http://www.acehardware.com/product/index.jsp?productId=3706810&cp=1260958 $799/free shipping and this 6" complete liner kit (broken link removed to http://www.chimneysweeponline.com/foreverflex.htm) Kit = $375 Putting them together in a nice new EFFICIENT, SAFE package. Total investment would be about $1,200 dollars. I will freely admit my novicity and undue optimism - so i would appreciate any dose of reality you can apply. I have attached a SCAN of my Firebox dimensions. THANKS.
