I don't know Ian...to me it's an over priced toy[Tyros2]...feels like one...looks like one...Compared to the Korg, the Pa1x[speakerless model] just feels and looks like a top pro arranger...and although I havn't checked out the Roland[G70], I believe it will surpass the Yamaha in quality...

I also think you get what you pay for......in my case it will not be a Tyros2
