Depending on your price range - you have a lot of choices.
Look at all the major brands: Hot Springs, Sundance, D1, Marquis, Artesian, Master, Coleman, ...; I'm sure I left a few out. It sounds like you should stay away from Cal Spas and Thermospas - they don't seem to be any good. My opinion is go to as many dealers as you can and make sure you like the tub and dealer. You'll be surprised how you like some dealers and don't like others. Check out models with and without loungers.
Another one of my opinions is to forget about ALL the sales dribble you hear and get the tub YOU like! Don't worry about full foam vs thermo-pane insulation or filtering or anything else a salesperson is trying to sell you. I would say all the major manufacturers have everything covered but they do things differently.
Also, people say WET TEST. I didn't (wife would have divorced me!) but I think it is a good idea.
Good luck in your search and I'm sure more experienced people will respond and give you additional advice!
