Hi, and welcome to the forum.

Although a lot of this info is dated for a few years ago, what you see around here is still valid. The best avice I can give you is to search around the forum (if you can see the blue links in my sig, use the Google search function linked there, although you may have to log out at first to be able to see the results--once your registration is complete, you should be able to see the whole forum without logging out). Good luck on your purchase!! (BTW, just a piece of info--if you buy a used liner pool, and the liner has already been installed once, you need to plan on replacing the liner--they don't empty, move, and then set up again very well.
