Recently the Privia series have gotten pretty much rave reviews with the lastest being the PX-330. Keyboard Magazine gave it high marks for not only the AC. Piano sound but also the nice action of its fully weighted key bed. Remarkably, it weighs under 25 lbs as well. The only thing that held me back from considering it was the lack of a Mod wheel. It does have a Pitch Bend wheel though. The price is an added bonus too.
FWIW, Mike Martin (formerly of Yamaha U.S.) is also now working at Casio too, although in the marketing department from what I understand.
Hopefully Jim Presley?? could convince Casio to put a Mod wheel on the Privia to go with its Pitch Bend wheel (or a combination Mod/Bend Stick)?? The Privia PX-330 also has arranger type functions on it too. If Casio made a full blown arranger in the Privia line it would probably be a huge hit since it would have 88 keys, be fully weighted, have a Mod/Bend wheel or combined Stick (hopefully), be reasonably priced, lightweight, and did I say have 88 keys?
The new Privia's also have 128 note polyphony as many of you already know.
All the best,
Mike
