Vita Spa's are owned by Maxx Spas. They share a lot of the same technology. They are not one of my top choices but they don't suck either.
My top choices are Hot Springs/Caldera, Sundance and Artesian. Most Maxx Spas use perimeter insulation. I'm not in the camp where this is better than full foam. They are usually easier to work on but they are not as well insulated as a full foam tub.
More important is the dealer support. If your dealer sucks, your service will suck. Warranty is covered by the dealer. It's very necessary to ask the dealer questions about warranty and if possible, speak to others who have bought from the dealer.
