I own a 2003 Geneva Utopia. I opted for the top of the line,as I can adjust the power/therapy needs.
I would suggest a wet test is in order.......and I would see if you can wet-test/compare the Utopia series alongside the Paradise series.
The removal aspect of your spa,and that being included with the price of the spa,is a great deal! Sounds like you have a good dealer,willing to work with you.(dealer a big equation in your purchase,now and future needs)
If you have time,view/wet-test Hot-Springs,Caldera,D-1,Jacuzzi,Sundance,Marquis.....in no particular order.
