Congrats on getting a monster of a spa.
I have a lot of experience with marquis, and the Epic is certainly one of the nicest tubs on the market.
It has two huge pump/motors and it's controller is Balboa which is by far the best on the market.
I haven't seen one with the constellation lighting yet but it looks cool on their website.
A quick word of advice would be to take apart the tri-zone diverter valves once in a while and clean them out with a hose. They tend to get sticky after 6 months or so, after sand/debris get in them. Just make sure you kill the breaker before you try that.
You can't regret buying a spa that has a floating remote.
