I think you are mistaking on the sundance. I just bought an arctic but the sundance was a close tie. I mean really close.
The 2005 are beautiful tubs. the optima at 485gal the new microban disposable filter. I have to say that they have one of the best filtrations that I have seen to date.
If your issue was with the dealer hounding you and dropping the price, I would wait and see how far he would go, less cash spent the happier I am.
Price should not be a factor, if you think about it, 1000 now extra for a good tub saves you from spending it later on big repair bills. Tubs are a luxury to enjoy. have fun with it and enjoy it. Im not saying im full of money, because I sure dont have alot of it, but I guess in my opinion tubs are a nice to have not a need to have. Get the one that feels good for you and you will be happy
