The Sundance Hartford comes with a cover, chemicals, a cover lifter, has the clean ray ozone generator, built-in stereo, LED lights, and free delivery as well as free water tests, and also comes out after we've set up the spa to show us usage.
The Hot Spot Tempo comes with a cover, but the cover lifter is extra and I can't upgrade the filter system, but I do get free delivery and lights.....however, the dealer is further away and not just a pool and spa dealer.
I'm sure the Tempo might run me a bit cheaper - I can always buy a sound system for the deck, but I'm wondering if the Sundance is a better name and worth the extra $$
