Welcome to our forum.
Have you looked at the Hot Spring Vista or Envoy? You can get all the cool features you are describing...lights, water features, jets, sounds, lounge, even TV.As everyone says, wet test, wet test, wet test.
I have a J 465 and can say that we love it and have never had a problem. As far as you saying it sucks, well you probably suck....Sucks is a bad choice of words.
Congrats on a great spa. We have that same set up at the fair for next week!
