Sorry for the large gap between posts, but I wanted to close the loop with everyone that provided all the helpful information. I ended up getting a Caldera Niagara. I love the feel of all of the jets, the look of the lights, and the space to move around. I'm quite impressed with the dealer who was pretty low key - he let the tub speak for itself. After the purchase, he walked me through all of the maintenance and was readily available by phone to answer all of my stupid newbie questions. The delivery guys were very professional and careful with the tub and with my landscaping. I couldn't be happier.
Well, I could be happier. I got the tub on 7/21 and left for a two week vacation on 7/29.
I miss my tub!! Thanks again for all of the great advice.
