Not if he had HEARD the DNC stuff, or SA2, I would imagine, Ian Get him to listen to the latest PA2Xpro OS2 DNC demos (and all the Yamaha SA stuff) before he makes a decision... Once he knows how big a difference thay can make, perhaps he'd have a different opinion?

Here's a thought... PSR's have a 'remote channel' that allows an external MIDI keyboard to mimic the arranger's one (so splits and stuff get mirrored). An 88 keyboard controller that could send the MIDI commands for arranger functions from it's buttons and sliders could trigger an S900 (or a nice used T2 ) that gets left in it's case out of the way...

All the great sounds of a Yamaha, with an 88. Still only one keyboard (on stage, anyway!).
