Hi Nigel!
If you need an FS1R - THey are discontinued.
Songbird (in Ottawa) have one used. Here's a link:http://www.songbirdmusic.com/ottasp/index.asp

As for SY77....
Most guys that complained were probably not to keen on programming. One of my friends has one and he just confirmed what you said.
There's nothing odd about it.

By the way, How do you like the FM7 soft synth. I think it's the only software puppy that responds like a piece of hardware.
