Welcome to our forum.
Have you checked into Catalina hot tubs at all. We have had our 06 model for about 3 months now and love the tub, it is great.
The local Sundance dealer wants $8800 for a new Optima, and that's the sale price and base level.
The Envoy is a great tub, however........The Optima is every bit as nice (if not nicer ) I would have a hard time justifying the extra $1200 for the Envoy if you don't want a stereo. If you do want a stereo they run about $1000 on a Sundance. If it's a lounger that your wife needs the Sundance dealer should be able to do $8800 on the Cameo(same size as Optima,different shell)BTW - I sell the Optima & Cameo for $9500 so you did get a good price.
 The one thing I love about the Envoy is with the back two seats.  When I use it, I take the Rotary jets out of the top of the seat next to the Captain's chair and replace them in the spot where the two directional jets are in the bottom of the other corner seat.  Then put the directionals in the other seat.
If you can get a good deal on a floor model go for it. Have you only looked at HotSprings and Sundance? Might increase your search to some other brands and above all...WET TEST!
