Yamaha released a new P-515 to replace the P255. Wood white keys is the selling point they are emphasizing in the videos.

I've been looking at the Privia's and the Yamaha 155 for a while now and can't make up my mind. This might be what helps me to "make up my mind." Yamaha definitely does have an edge over the Casio's in authenticity, but....it's not exactly a lightweight. Last I heard........the Casio's weigh no more than 2 lbs 3 oz
. They're screaming...."buy me, you can carry me around in your lunch pail!.
I'm going to call SA tomorrow to see if they have that model on the floor.
