Naziz,

I have talked with Sythplanet and prices are quite accurate.
The only problem is that they don't have SD-1 currently in stock and you have to wait until it arrives. They told me that for SD-1 they can not estimate how long you have to wait because there is so many people on the waiting list but they still accept orders for the price that I have mentioned above(US$1732).
I think that SD-1 is quite specific case because there is no so many Ketron dealers all around the world so you have to wait for your turn to get the SD-1. It makes sense.
On the other hand PA80 is available in 10-15 days and its price is US1247.

Regards,

D.
