We bought a NIB 16 x 42 Summer Escapes Metal-framed pool off Craigslist. Needless to say it is missing the pump and filter. I have not had much luck finding a replacement pump, the one I did find was $140. What are my options to get this thing up and running, My kids are so dissapointed! I have been looking at saltwater pump options but don't really understand how it all works since this is our first pool ever and so far a horrible experience. Please HelP!! Any advice is extremely appreciated!!
