I have seen in other threads that many of you have used ebay for chimney liner purchases. I was wondering if any of you fine folks have used this one: http://cgi.ebay.com/6-X-25-Stainles...hZ019QQcategoryZ20598QQtcZphotoQQcmdZViewItem If not, do any of you remember who you used? Of course only want to see the good ones . I'll pass on the vendors you had not so good experiences with. I have seen at the stove shop, there is a heavier one that the ribs are wider & it appears smoother inside, and then the other type that has smaller higher ribs and honestly that one felt really flimsy. I think the thick ribbed smoother one I saw was Ventinox? Anyone familiar with them? Thanks oh wise ones!
