I am in the market for a shower massage, and am trying to compare the Dream Spa offered today with the Total Spa offered a very short time ago, and whether I should purchase the Dream Spa today or wait for the Total Spa to reappear in a future Woot sale. Yes, the Dream Spa has a bar which allows flexibility of where to mount the hand-held unit, which the Total Spa does not. The Dream Spa also offers 7 functions, whereas the Total Spa has 5. That being said, one of the functions for the Total Spa is a "Stay-Warm Mist", which got rave reviews, especially from people who like me have sinus problems. This is not listed in the 7 for the Dream Spa, unless "Rain/Spray" or "Rain/Massage" is the same thing (does anyone know)? Also, I am trying to determine if there is any difference between the two models as to what (besides the flex hose) is metal, if anything. Thanks.
