Ian,

that is a bold final statement coming from someone as dedicated to Yamaha as you are. But I cannot find fault with your arguing. " Au contraire ", I would say that for those owing a PSR910 they could save themselves the expenditure for updating to a PSR950 and use approx. the same amount of money to get a brand new Korg PA600 on top of the PSR910. Not quite probably ( moneywise I mean)but pretty close I would reckon....

regards
John
