Whatever happens, I'd be content with one of the current crop of arrangers for the rest of my playing days...either a
Yamaha PSR-S910 (or the next S-series) or a
Yamaha Tyros4, which I am seriously considering, now that my demo Tyros3 is sold. I'd also be quite happy with a
Tyros3 or
Tyros2.
I don't want a
workstation 
...I'm VERY lazy, and they are too much
work; hence the word "work" in their name.
If I really
had to do without an arranger, I'd go the
Band In A Box route.
