I'm looking to install my own liner in an existing masonry chimney with ceramic tiles in good condition. I've seen Simpson DuraFlex and a brand called Flex King online, but have heard rumors of shady internet liners. Are these liners junk, middle of the road, or quality? I know Simpson voids the warranty if the liner isn't purchased from a authorized dealer and installed by a qualified sweep, while Flex King claims their warranty is valid with owner install. These liner kits are being sold for under $400 (25') and shipping is free. Too good to be true? Is there another liner I should pursue that is reasonably priced?
P.S. I've spent about two hours today searching posts and needed to ask this question directly. Thanks.
