Mainer,
You're right about the high price of keyboards in the states. I think the difference in price is because Americans make higher wages, on the average, than people in foreign countries. The local dealers here know people will pay more, so they charge more. Markup on most items is usually 100% or more. Even though the prices are lower in foriegn countries, it is usually best to buy locally, mainly for the warranty and availability of repair work. I was told by the Technics dealer where I live that, if you buy from overseas, your warranty will not be honored in the states and you won't be able to get it repaired here. Our prices could be higher because of import and customs fees. I would expect that these are also added to the price. Of course, this is all my opinion and others may have different information available. I guess the high prices and lack of availability is something we are going to have to live with.
Best regards,
Peter
