S70 xs
and I can't understand the reason not making PSR 910 with 76 keys and sell for 2000$.
They'll sell pretty well.

The S90xs is 45 lbs - in the same category as a Roland G70.

I have come to realize that the PSR series is in and of itself a home keyboard. Yamaha has been true to its philosophy and kept all the PSR series a home keyboard - plastic body, smaller & lighter keys, just enough TOTL features to attract semi-pro and pro players. The exception to that philospohy was the 9000 "Pro," the precursor of the Tyros.

Yamaha's pro keyboard is the Tyros series. the build quality is better, as are the key feel and features.

Yamaha has the makings of a 76-key board in their YPG625. They just refuse to go all the way with the arranger concept.

S70SX is a fully weighted 76, same as an 88 wood... not surprising it weighs a fair deal.

Still think if Yamaha made a lightweight 76 S910, maybe the NP10 keybed, expanded S910 case, the thing would be maybe 30 lbs. or so. Got a feeling this would be a seller, but Yamaha have no interest in making it. They THINK they have that market covered with the YDG's, but personally I think they are selling us short. They may have the action, but they certainly don't have the arranger we want...
