You are probably right John when you say, "I also feel the desire for all arranger keyboards is diminishing." I believe it is a dealer that has been trying to sell a Roland E80 on eBay for months and has dropped the price from $2,500. to $2,000. and still no takers. As I understand it, this model is a very good keyboard and on par with the KN7000. Personally, I am so satisfied with the KN7000 that I am not interested in newer keyboards. I have put entirely too much work in the KN7000 to lose it for a new play toy.
