If you are looking for something that will last forever without leaking and that is a DIY project, a one piece fiberglass is the answer. They come in several sizes and shapes and are fairly easy to install. They need no maintance other than normal cleaning. Of course, you should have access to the back if possible as someday you may have to repair/replace the valve, buth that's true with any type of installation. As far as brands are concerned, I don't know how many choices there are, but I doubt if it makes much difference, they all will be made essentially the same way so find one you like and that is the right size and configuration.
