I believe it's all marketing, whatever price the market will bear contributes to setting the price.
marketing? I can understand, but and almost $2000.00 price difference has to be substantiated in any event,.....let's not get off track and get to to the decisive answer of what constituted that major difference in price between the two and lets also throw in the Ketron Sd7/9 too price wise....
PS: is the new GENOs going to be the first arranger to top $6000.00 next also are we headed back to wooden home organ prices soon!!
