Stuart's right on The Caldera is almost twice the money as the GL and you get what you pay for. I have owned a GL Ottawa for over 3 years now and have not had any major issues, just 2 minor issues that were both taken care of immiediatly. One jet failed (the bearings fell out and it stopped spinning) they sent me a whole new set of jets (musta been trying to get rid of them cause they don't use that style anymore. And a neck jet got sticky to turn for opening and closing (they also sent me 2 new neck jets and the tool for loosining it.
Other than that great tub for 4 grand, no bells and whistles, simple and seems reliable.
