I've been thinking of getting a hot tub. I've read some stuff online but there is so much out there that its confusing as hell. Anyone have recommendations/suggestions/etc? A few of my questions are: 1. There are SO many brands out there. Is there a big difference between the low price brands and high priced brands? 2. Should I buy new? There seems to be a pretty good discount by buying used but not sure that's the best route. 3. Any key features I should get? 4. Is there a "best" time to buy one? They are all over the state fair but I've heard there are much better deals out there. 5. Any recommendations?
