Same here...
Really don't know if I can trust them...
My wife really like the "Chiller" for getting the water a little bit less hot during summer.
My Friend has a Sundance for 13 years, and seems very happy with it, and the Internet seems to like it more too
I think my choice will be a Sundance at the end... from what it looks like, its a little bit cheaper than the Artics Spas, better reputation overall
Ive looked for the Trevy one, but I really dont like Trevy from past experience, so I dont think I can buy something has complicated as a Spa with them. (Just my 2 cent).
