After Dave's wife, Roberta, died, the company has been held in trust. Ken is looking to retire and I don't know that he's in a position to buy it anyway so it will be sold. Ken told me a couple of months or so ago that there is an interested buyer and I think he said there are delays caused by the the settling of Roberta's estate. He didn't have an expected time when the sale would be finalized. He gave me the feeling that we would end up being comfortable with the result - in other words, the people who are interested are knowledgeable and enthusiastic and not just a corporate drone. That's about all I remember Ken telling me about it and I don't think there was much more Ken could tell me.
I can't say that I'm looking forward to the new buyers taking over. I suspect Ken will probably leave shortly after. I've really valued his advice and technical help over the years. I also expect that it will be ok though.
Incidentally, the same thing is happening at r.d. enterprises. Ray is on his way out and at some time George will take over.
