Rik, thanks a bunch for the reply. Sorry I was so long to respond. We actually pounced on used tub a few days ago. It's a "Four Winds" "Honolulu" tub that was bought for over $10,000 16 months ago (receipts were provided), which we stole for $3,800. It's not a "big name" tub, but it's still well within warranties and appears to be in like-new condition. The seller's circumstances turned out to be very advantageous for us, to say the least.

Now I'm just doing some research on how to maintain it, what chemicals to use (and not to use), and planning for the hydro to be run and work to be done on the deck to build it in (with maintenance access, of course). Wish us luck!
