Although I still own a Korg and used to own a Ketron, I'm with Ian on this one.

I think Yamaha have created the most complete keyboard out there that wouldn't sound out of place in whatever arena or audience you play in. Maybe the same could be said for Ketron as well but the Yamaha seems to be more attractive to play.

Whenever I've owned a Yamaha, I've always never thought it dominated in any one area, it's been balanced right through and I have always found a style or sound that's useable for all the music I play where as with my Korg or Ketron, it ranged from sounding exceptionally brilliant to really horrid or I struggle to find a sound or style that was suitable. I've never had this problem with the T3, every day I find something that's better than I found the day before about it. Amazing keyboard.
