Comparing the WERSI with those plastic Japanese boxes is like comparing a RollsRoyce with a ordinary midclass-car.
It just make no sens.
I own a WERSI OAS 7, and I can only say :
"Nothings comes even close to my WERSI !!!"
(BTW, anybody wants to buy a Ketron and Yamaha ?)
Have fun everybody with your "plastic toys"
