Local prices for a kit like this were around $1,800. I paid $464 for the FactoryPure. Unfortunately, the directions were two steps below basic, and there were no photos or diagrams. Basically, the directions consisted of "Insert and tighten." I took my time and figured it out myself. I took pictures along the way, and I wrote out detailed directions, which I am going to send to the manufacturer. I was able to do most of the installation myself, using an assistant only for lining up the opening inside the house. Overall, if you want a chimney liner, this is the way to go.
