a very nice spa for the dollars spent is the Marquis Quest...I have said it before I am a big fan of this spa...and YES I am bias....but I really think it is a great value....a nice spa that is quiet...comfortable and can accommodate 4 when needed...but as most spas get used by 1 or 2 at time about 90% of the time.....it fits a lot peoples needs.....
