Question for the pool owners....

Starting the process of looking at getting a swimming pool. Everybody is saying a salt pool is alot easier to maintain. Also looks like the fiberglass is more expensive up front, but will be cheaper in the long run. I've had several tell me they have had problems with liner pools. Give your opinions and what I need to look at. We are looking at a medium size pool that is only about 6 feet on the deep end.
