I strongly suspect that most of the liners are made by a few manufacturers. Both my liners were put in by different installers, but were ordered from the same company. What I have found, though, is that the warranties are different from company to company, so that would play a large part in my decision if I were buying another one.

Some liners are 20 ml thick on bottom and sides, some are 28 ml on bottom and 20ml on sides, but overall I think the difference lies in the warranties. Honestly, if something's going to tear through 20 ml, I don't think that extra 8 ml will make any difference!!
