I agree with hottubguy. the Marquis prices are very low. The V84 is a really nice tub, and I also like the Broadway Elite. I own the 435, which is the very similar predecessor to Broadway in the Celebrity Elite Series.
All of the E-Series will be discontinued by 8/20. Celebrity Elite is the replacement to E-Series. There will soon be a Celebrity Elite Vegas model which will be the next generation of the 750 (open seating/no lounge).
Good luck in your search, Marquis is a great tub and company to deal with if you go that route.
