mattwnz:alasta: My father bought one of those around the same time and it was an absolute lemon. So much so that I have avoided Mitsubishi Electric products for over 20 years, but this year I gave in and bought an Oasis dehumidifier which admittedly I'm very happy with.
I have found the opposite. Have two Mitsubishi oasis dehymdifiers, and both were lemons, as both 'degased' after a few years and stopped producing water. Had them regased, but that only lasted another year before they degased again and stopped producing water. They weren't even used that much, but were about $800 each. If I had known about the CGA back then, I would have got them to replace them.
Mine's only six months old so it hasn't had the chance to prove its long term reliability yet. The reason I bought it is that the cheap one I had previously was far too noisy and the Oasis seemed to be the only model I could find that promised acceptable noise levels.
Time will tell, but if I get a 'few years' out of it then I won't be too bothered.
