Oh boy, I have a few comments.
First, for fernem -- why don't you tell the dealer who is holding your money that you want to wet test a vanguard and whatever other model you think you might like. I know my wife and I liked some manufacturer's lounges and not others. On Hot Spring, which we did like overall, we did not care for their loungers. We (if we go HS) would either go for Vanguard or Grandee. We like the extra seat in the Grandee. There is a member of this forum whom I trust that sells HS, and he says the MotoMassage in the upright tubs (Vanguard, Grandee) is not significantly different than those that put the Moto in the lounger. Give them a whirl -- best chance to keep your deposit.
On the 3 day rule, that's not a nationwide thing. Dr. Spa is correct. Not every state has that. In my state (IL), there is no 3 day rule on ANY contract -- even one that you sign in your home -- unless federal law provides for it. The only example of a federal law with a 3 day right of recission that I can think of (off the top of my head -- which, admittedly, is numb from the way the Bears sucked tonight) is a closing on a refinance. There is a 3 day cancellation by federal law.
