First and foremost, Bachus thank you for your views and advice,
much appreciated !!!

I will be testing the CP5 later on today. For me there are only three or four essentials. Obviously the main acoustic piano sound ( though I do not worry too much about that), second the keybed and key action, ( the action on my old yamaha P80 is close to perfect.....) and third, apparently the owner is a smoker. Now I have nothing against folks who want to smoke bad as it may be for you but I once or twice bought an arranger keyboard (unseen) which turned out to be reeking of smoke beyond belief and take it from me, there is preciously little you can do about it. As I will only be using the piano within the confines of my music room at home this becomes an issue. And of course the price should be right.
To be continued............

regards
John
