someone is selling an oasis that has been installed for one season semi-inground looks to be buried at least 36” have not asked for exact depth, and will disassembled and deliver it but they are asking a price that is comparable to a new intrepid from the pool factory (new without pump and filter but our current ones knock on wood still work so we were planning to reuse those for now). we would be using the pool fully above ground and wanted advice on whether to even consider the used pool or just go for the new one with full warranty?
