Okay, so y'all probably think I'm a flake at this point after going from almost taking a free, beat up hot tub and then changing my mind.  When opportunity knocks, sometimes you have to answer the door.  This may not be as great of a deal as I'm thinking, but I love the tub and I'm happy with the price. 
I went to a local Jacuzzi and Sundance dealer in Scottsdale to check out their 4th of July sale, and I was not disappointed.  The salesperson was really cool and laid-back.  No pressure at all.  He asked my budget and I told him 8-10K, but could go a little higher if needed.  He showed me 3 or 4 tubs in the 8K - 9K range, and I just didn't fall in love with anything.  I think he got the feeling it just wasn't going to happen, so he just started talking (the place was surprisingly pretty empty, but it was mid-afternoon).  So as we were meandering around, I saw a tub with a sign that had a bunch of red stickers on it that caught my attention.
It was a 2017, 3-month-old Sundance Cameo that someone had bought in April and returned because it was too deep for he and his wife, so he traded it back for a different model.  I don't know the accuracy of the original price, but the tag and the salesperson said that it was originally bought for $17, 500 and change.  They had it marked down to $12,999.  They did not have one set up for a wet test, but I did a wet test on an older model Cameo a couple of years ago when I first thought about doing this, which is where I fell in love with this tub.
In any case, after some more conversation and some gentle negotiating, we agreed on $11,500.  Here is what I got:
2017 Sundance Cameo 880 with Celestite Shell and Coastal cabinet.
Gray Sunstrong cover
CoverMate I lifter
Awesome steps...three full no-slip steps with a handrail.  I've actually never seen those steps before and they're awesome!
Clearray UV
Pro3tect low-output ozone generator.
Full manufacturer's warranty (this was my only concern since it is used, but they're still treating it as a new purchase).
And I got 4 years financing at 0% interest.  All in all, I'm really happy about it.  It's a bit more than I wanted to spend, but it's one of the tubs I really wanted (and had crossed off my list due to price), and now the only issue is that I want it NOW!  I'll post tome pics after it gets delivered.  I still have to get electrical set up, and that'll probably be next week.  Very excited!!!
