Query: poor parts availability

I have a Bionaire CM-1 that was used very little. However the plastic in the tank cap deteriorated and the cap fell apart. They do not stock this part even though there are numerous customers on internet looking for it. I did not want a freebie but just to purchase the part. It is a shame to have to throw out a good humidifier because the manufacturer does not support with parts. I would assume that this applies to all their units and would not buy from them again.
