Get an Intex metal frame, above ground pool - the blow-up models are not reliable. Intex has the most consistent quality of lower end pools. This is the third season we've had our Intex and it has been WELL worth the money. We upgraded to a sand filter this year because the Intex cartridge filters don't do a great job(almost worthless with the Intex brand filter) and we didn't know there were higher quality cartridges available. Also, a 2 hp pump is way more than you need, and cost more to run. A 3/4 hp will probably work and 1-1/2 will be plenty.
