It's really hard to get an impartial review here on this board. Whatever people own, is what they recommend. Only the few who have owned them all can really give an objective review. Unfortunately, I only own the Tyros 2 and that is why I recommend it. I have researched the other extensively, the bottom line for me were the glorious samples and styles of the Tyros 2. I must admit, I miss 76 keys and some of the other bells and whistles, but at the end of the day it's all about not sounding cheezy.
