thanks to all of you I have narrowed it down to these. No the major question-which one! They seem similar-configuation, # of jets, warranty, etc. Both salespeople had a great "rap" But the price: the envoy was quoted at $8500 plus $400 for the Everfresh sytem. The Optima was quoted at $8595 including ozone system and a step (step is extra for the Envoy). What do you think? Note I have not negotiated at all with either salesperson as I am waiting until purchase but each told me there is no "room!" Any thoughts?
