We bought a Caldera C45 from a dealer and after two years of light usage, it stopped working. After two months, five service calls (& too many phone calls to count), and three replacement pumps, it still does not work. I have been in contact with the manufacturer over a month ago and they are as unresponsive and dis-interested in solving the problem as our local dealer. Run, don't walk away from Caldera. It may cost a little more for a better product, but worth in the long run.
