I understand fully the perspective of George Kay. Live performers embracing any keyboard cannot be the measure of the best keyboard for very simple reasons. I have been reading the posts of Uncle Dave and others and I have all respect for them and for what they do. But I believe they have totally different needs than other musicians like myself. For me, I need a keyboard that allows me to do everything and control everything EVEN if there is huge learning curve at the beginning. For me I embrace my keyboard until it dies. For them, they are willing to switch keyboard every six months, their professional careers does not allow them to spend the time to program a style from scratch or to adjust the velocity of a particular note for a song on the sequencer. They need something to do the best job right away. They cannot afford to spend six months to learn a keyboard

So when George Kay ranks SD1 to be the best... he is using the absolute scale regardless of the time to learn the keyboard. So I always say what is best really depends on what is IMPORTANT FOR YOU. What you regard as best. For me, Sk880 is the best now because it has some features that other do not have that I deem very important....although.....others may beat it in other features such as sounds...
