Hi.
This is were we bought our new pool from.
http://www.sunenterprises.com/abovegroundpools.htm
The pool in the middle called the Ultima is an Artesian.
We just bought and installed the 33'round. Even tho they call it the Ultima it is still an Artesian- they are just allowed to give it their own name.
If you call them they will answer all your questions and concerns.
This is a great company to buy from. Their customer service is primo!

Good luck
