Well, that list is pretty incomplete if you are simply asking what we would use if we could NOT use our current arranger. Where's the Audya, the Yamaha's, the Wersi's, etc.?

It IS a tough question. One I answered for myself this week, in a way. Were my G70 to die, I have bought a backup G70! Were none available at any cost, that would be a devastating day. I need a 76, so there goes the Yamaha's. I need easy editing and customization, there goes the Audya and SD-1. I need an easy to use OS and plenty of fills (and a better piano and B3) so there goes the Korg's.

I just don't know... And I have a sneaky feeling that many would agree with me. If we COULD happily play something else in comparison to what we own, we would already be likely playing it!
