for 7k that Glow is a nice little package, 5yr component warranty, 24hr silent circ pump, a good 2lb FiberCor insulation and even though I'm not much of a "bells and whistles" guy the lighting and waterfall are pretty dang cool (esp. if you have kids)....my fav. part of that spa is the fact that its a 2 pump (2.0hp each) tub with 30 jets which in turn makes for some very nice strong jet pressure...I don't have any hands on experience with the J-325 so I can't comment much on it but I can tell you both Hot Spring and Jacuzzi are very reputable manufacturers, and as always a wet-test, dealer competency, etc. should also be factors in your decision
