I wanted to see if I can get some real world information on pool liners and what the people that use them have found out. I am pricing liners for my 28' (according to doughboy) pool. The liners I am pricing for them are very very expensive. To the tune of $920 for a 20 mil doughboy liner. GFI liners seem to be much cheaper. Can anyone tell me if the extra cost is worth it. Thanks. I will be strating excavation next week. I havent even thought about plumbing Lots and lots to do.
