I (personally) would NOT recommend the KN6500 if 'techno/dance' drum sets & sounds are at the top of your wish list.

I think that the Technics KN keyboard's big claim to fame are its' great traditional swing jazz, orchestral, & latin styles, but its' contemporary styles & sounds are pretty weak (imho). The Technics drums don't have the 'in your face' PUNCH the SD1 provides and The Korg PA80 has a lot of great contemporary synth sounds based on the legendary Korg Triton. For your needs, I'd pick between the Ketron SD1, XD9, or Korg PA80. Just my opinion. - Scott
