Purchasing a pool and have no answers

I live in PA and looking to purchase a 15 x 24 pool. I was looking at a Buster Crabbe pool and recived some information from two pool stores. My questions are: What do you think/reviews on Buster crabbe pools, what are better steel or aluminum, the pool likt comes with a 1 1/2 hp Pentair filter, what are your comments/reviews on the fileter, which by the way is a sand filter. Also what are your thoughts on a sand vs de filter. please respond so i can have the most info before i spend the money
