As I have said in may other posts in other threads, there is no perfect keyboard. Some people may prefer the T2's clean sound, others might find the Korg's electronic timbres appealing, yet someone else may prefer the live styles of the Ketron. They are all right - every keyboard has its own strong points and shortcomings, and someone may find one or another board a greater inspiration to them. No need to start a big argument here.
I personally like the Roland sound. So I voted with my feet - I bought a G70.
