Thanks for the information, it was helpful.

If price was not a factor at all, would you recommend the Casio PX400 or the Roland RD170?

As for external speaker systems...

Would the RD170 absolutely require one? I play guitar and have a guitar amp. I've heard several times that playing bass through a guitar amp is not very healthy for the amp itself, do you know if this holds true for digital pianos as well?

Could you recommend any decent external speaker systems?

Thanks a lot, your help is much appreciated.
