Dave,

As you can see in the video, see link below, I already had the P255 for a short while. I do agree it is a nice piano but I was not as enthusiastic about it as you seem to be. Particulary the internal speakers, though loud enough , did not wet my appetite.
For use at home you should try and connect a set of Creative T10 ( very cheap really) and then already you will hear a lot of difference. As to gigging I have no idea.
Tomorrow , unexepectedly , I have to go and see a Yamaha CP5 which is on sale at close distance from where I live. I am sure Bachus will fill me in on the merits of it !!
