Marcel,
the contenders for the title of best digital piano at the moment are:
- Gem Promega 3
- Roland RD 700 SX
- Yamaha P 250
(in alphabetical order!)

The Kurzweil is still an excellent choice, but right now seems one step behind the others.
My advice: try and play the first three (it shouldn't be a problem where you live) and then make up your mind.
