I would echo your sentiments Cal. It seems that personal agendas take over many times over providing good information.
As my family has been in the car business a long time (50 years), I know how it is to be overly biased about one product over another (trust me on that one), and the ensuing debates.
Having said that, what also drew me to this board initially, was exactly what the title said "what's the best hot tub". I was looking at the time for a new spa, and 75% of the time still find good information here.
I would suggest, IMHO, that some of the threads (specifically recent ones) would be better left to private messages or emails than posted on this board.
