1) Roland E 20
2) Roland PRO E
3) Roland G 800
4) Roland VA7 (I guess I was a Roland guy.... ), then
5) Ketron SD1 and
6) Yamaha 9000 pro (together with the VA7); later added a
7) Ketron XD3... finally sold everything and bought a
8) Tyros.

Future: Tyros 2 and (likely) Roland G-70 (if OS 2.0 holds its promises...)
(Owning two arrangers is better than owning just one Three? Don't know: it gets complicated to pick one to play)
