I'm seriously considering one of these new pianos by Waldorf. Nice flat top (for the Tyros4), with 76 keys (that go down to low E) and from the on-line demos I have heard so far, a super instrument, although probably a little pricey.

Then again, in some cases, you actually do get what you pay for.

As far as Arranger Keyboards go, anything new is just not on my radar as the Tyros4 is more than enough for my arranger needs...the Tyros5 wasn't enough of an upgrade, and after using the T4 for some time now, it would be difficult to go back to the much lighter and shallower actioned, non-aftertouch, PSR keybed.

I suspect Yamaha will be replacing it's long-in-the-tooth Motif line very soon, and I figure the S950 replacement won't be out until the fall or later.
