Hello Grunt
My wife and i have had the jacuzzi 480 for about 3 month now.
It is a very good tub for therapy, i have had lower back problems since my teens,also i do alot of driving during the day for work 40 minuets in the tub really loosens my whole back and i now sleep though the night.
Having said that, the two things i have had problems with are the pillows and stereo.
The pillows will not stay on. jacuzzi must go back to the drawing board on this design!!!!!
the clips on the tub are not long enough. So the pillows hit the tub but the clip in the pillow will not hold on tight enough, the slightest touch and they fall off.
As far as the stereo I'm on my third one. The first one would not play a CD. second one worked for five minuets then went dead third times should have been a charm but the remote doesn't work. the remote works through the stereo. If i had to do it over i would be soaking in a tub with out the stereo and saved the money spent on it, but as a first time buyer i wanted it all. Other than these small problems that my dealer is working on this is a first class tub!!!!!
As for the foot dome its a 50/50 when you want some foot time there it is when you don't you simply stretch out. as with any tub there are more ways to get comfortable than just sitting in the seats. Some times i put a float under my head and upper back and just relax.
I'm sure you and your wife will love any of the three spas you are looking at
Good luck
