Hey Chas...
I was there for 2 days....attending classes on day 1 walking the show on day 2......interesting the difffrent makers who were at Aqua and not NSPI.....the names at Aqua....Sundance.....Marquis.....Jacuzzi.....Master....Artesian.....Caldera....were not at this show...the bigger names who were would be Cal Spas....whose booth was pure Vegas....and D-1....and than many of the flashy makers....I did not see much that impresseed other the classy look of D-1...I think a very nice spa....but pricey.....there is a great new tool for fliter cleaning that does a great job and is easy to use....
