I'm looking for something like my Kurzweil SP4-7 but with updated (and better) sounds, lightweight, hammer action (not as light as the SP4-7, not as hard as the Roland RD 700GX), being the most important part the acoustic piano, electric piano (especially Wurli), hammond, and strings. I don't need rhythms, nor internal speakers, nor a workstation, just a stage piano with light action.
I've taken a look at the Casios (my 1st stage piano was a Privia, great piano for the price), they look great but I don't know if a touch screen is a good idea, I'll be moving it a lot from home to rehearsal and to the stage (hopefully). And the noisy action is a problem for studying at night at low volume.
The Roland and the Kawai look great, but they're same or more expensive than the Kurzweil and same or more heavy too. Maybe acoustic pianos are better, but I prefer to sacrifice a little in sound in favor of weight and price. I mean, the SP-6 doesn't sound bad, right? The review from Legatoboy about the Yamaha makes clear the decision.
Thanks everybody for the suggestions!
