from the help and opinions i've rec'd on this site i will be tackling the liner install myself (SS felxible). Searching online i see a variety of pricing - the least expensive kits i am seeing (40', not yet pricing for insulation blanket) are ForeverFlex at approx $540 and FlexKing at approx $475...for the entire kit. And a whole bunch of manufacturers in the $650-$900 range. I prefer 316ti, probably will NOT go with smooth inner lining...I am looking for opinions (good or bad) from any of you who can share thoughts on brands/manufacturers. Thank you all!
