Just picked up this 2009 spa in mint shape and in running order for $5k cdn.  Im new to tubbing, but really looked into each used one that interested me and i was impressed with the design of this tub.  Anyone have any experience with them?  Are they as good quality as they seem?  Im commited now but would like input.  I love the clean mechanical chamber and the use of Roxul to insulate.  Unique and i thought a very simple solution to the problem TP and FF each can present.
