Aquarite Jr. rating

[cmack]

I've been looking into buying a swg. And found an Aquarite Jr. which is rated for a 20k pool. I live in Texas where we are currently at 90deg. plus for most of the summer. Has anyone had any experience with this particular unit? I've seen quite a bit of feedback on the aquarite goldline40k but zip for the inferior unit. Do they have the same Jandy interface. The units I'm looking at are offered by Blue Haven pools. at a pretty fair price.
any feedback would be appreciated.
Thanks
