sorry,,,to air my frustration..i apologize...
So what exactly IS your frustration poopsy? Why are you making this so difficult? You've wet tested, shopped and done the rounds, now it's time to find a spa that you like with good dealer support in the price range you are willing to spend and buy the da#n thing.
Have you hated everything you've tried? Were they all out of your budget?
I think sometimes people enjoy making this purchase more difficult than they need it to be.
It's a Nike commercial....... JUST DO IT! I'm sure you'll find yourself more relaxed once you do!
