I would tend to agree, the best selling keyboard that ketron ever made was MS40/50/60 at a retail price of 1700+/-.

the keyboards after the ms50 were major improvements but never best sellers like the ms series. I think ketrons are being put out at very high prices vs the market and what people can afford. Ketron no longer has a keyboard under $2000, unless the xd9 is still production. but even that had big problems. I being a very big ketron fan and owning most of the boards after the ms50 find myself wanting to turn to yamaha or a korg because of there price points. the last ketron I purchased was the sd5 and I offen think if I should had waited for yamaha s900 instead & (also save a couple of buck too).
