Audrey,
What type of dancing??

For the Fox Trot to Waltz type of ballroom dancing I do prefer Technics. For Latin and Contemporary ect. -- my choice is Yamaha. I fond Roland to be somewhere between both.
The Tyros 3 is expected to make its showing in October, if it is what I feel it will be I will buy it -- as my last keyboard investment. I would stay with my S900 but having played on Technics keyboards for so long I am spoiled. The S900 has filled my every need, it is a good keyboard.

Ah, in search of the perfect wave.
