Sorry, I'm sure this question's been asked before, but, I'm buying a free standing wood stove (Lopi - Endeavor) from a local dealer and am checking into installing it myself. The few dealers that I've gotten prices from, for pipe, all seem pretty high to me. Any where from $800 to $1000 for an approx. run of 14-15' total. I called Gensco (venting supply house) and their prices seem to be quite a bit less than the stove dealer. The stove dealer is selling "Excel" and Gensco is selling "Metalbestos" products. I looked online and found many different pipe manufacturers/retailers offering their products for far less than the stove dealer. Question ... Are the dealers gouging or selling far superior products? (sample cost excel 48" SS insul. 6" pipe $201.00) Are there brands that are worth the extra cost or should I just shoot for the "middle of the road" product? Is there a good source to research the stove pipe in general? Where can I find good info on installing a wood stove? Thanks, Mike.
