I'm getting an Jotul Oslo 500 soon and have no chimney yet. I had a professional installer come out today to give me a quote, they only do fireplaces and chimneys and seem to have a very good reputation and skillset. They want to use ICC's Excel chimey pipe, which is a brand I had not looked at yet (been looking at Duraplus and Selkirk mostly). The price they quoted for the Excel parts is really high (~$2850) compared to about $1500 for Duraplus and $1900 for Selkirk. He sung a nice song about how the Excel chimney pipe is the best available etc., but I knew to ask here for honest opinions. Is Excel pipe really worth the extra expense? I see it is rated to withstand longer chimney fires, but is that overkill?
Also does $500 for labor sound correct for thru the wall chimney installation? (I'm building my own hearth pad and putting the stove in place myself)

Average it with the cost of your liner on the other end of the house for a better "household solid fuel venting cost."
