Keep in mind that the TX is a single-pump system, with all the basic equipment. I have sold a bunch of them and they do a great job. But even though it does work very well, it is not a smaller version of the HotSpring tub.
What I mean is that the Jetsetter has a diverter, no-bypass filtration, a small silent circ pump, better warranty, more jet variety, bigger number of jets, LED lighting, two siding colors, several shell colors, more cover colors, cover lifts are available though the lid on the TX is a featherweight and really doesn't need a lift, larger jet pump, cleanup cycle, pump shroud, and a few other things that I can't bring to mind just now.
Not saying either one will automatically be better for you, just pointing out that the Jetsetter may be small, but it is built just like the $10K tubs HotSpring offers.
