Al is right that is a good price on an awesome piece of equipment.
I had a guy call me the other day that had bought an AQS 1200 from me 4 years ago. He manufactures medicine and needed to control the humdity. So he says he has had his 1200 going for 4 years straight. It never shuts off. They have changed filters on it and that is it. He then says he would like to get another 1200 because the one he has is wore out. I suggested to him that either his desiccant needed cleaned, he had a motor out or his belt was broke on the desiccant wheel. He calls back later and says that his belt was broke and he does not need a new machine.
That is just amazing. 4 years straight. That is over 35,000 hours and still going strong.
