Our pool/pump/filter system was just under $4000 with the winter cover solar cover and solar panel delivered. My biggest issue was that there were more uprights/shorter distance and size/strength of them for support, decent top rail and the corrosion resistance of the bottom rail (resin or aluminum - ours aluminum) as well as good liner and total warranty. Went with a buttress free.

All the ground prep will be around another $500-$700 (could have been more if we didn't own some of our own heavy equipment) THAT we want to make sure is right.
