I am from Germany and have just bought a SP4-8.
It was one of the last keyboards of this series, which are still sold new in Germany.
I wanted to buy one in 2012, but now the price was so tempting that I could not resist.
I have always been interested in Kurzweil Instruments and I have a Micro Piano Module.
I am happy to have found this board and I am pleased to be here.

Cheers
