I'm getting ready to install my second stove in the finished basement and am pricing the 3" pipe. My last install used the Excel pipe, which was very easy to use, but very, very expensive. I'm thinking of trying Duravent this time and have found it cheapest, and good supply at my local Lowes. Can anyone recommend a cheap source of pellet vent pipe, or recommend a brand that is the sweat spot for installation ease and price.? I'm not stuck on Duravent.
