Hammer, I just feel that the S900 for me gives the best bang for the buck. As close as you can get to a Tyros series unit without all the bells and whistles & higher pricing. It also has many useful features & the SA/Mega voices are outstanding. It's so easy to use, edit, and the support is by far unsurpassed for 3rd party styles, etc. I am not an expert, but as a home user I enjoy playing the S900 very much.
