I didn't quite care for Yamaha's recent weighted hammer actions, even on the CVP-609. I did get a quick go at a Yamaha CP-4 Stage Piano and liked it very much, so I believe it must be slightly different than on the CVP.

The past few years we've been using the el cheapo Yamaha P-85, and now the P-95, as controllers in the studio, mainly for the Tyros4. I have to say, I actually like their weighted hammer actions better than the higher priced instruments (the entry level P series do not have wooden keys) and think they are a great bang-for-the-buck if you want an inexpensive great feeling basic midi controller (no pitch bend, mod wheels or aftertouch), that's also lightweight and has a very decent built in piano sound.
