Same problem for me. What to buy. Everything I've read about a live board, along with a good studio piece is the Pro. I like the fact that it has expansion, I know the harmony is top notch, I know the sounds are top notch, I am familiar with the quick on-the-fly yamaha protocol. The support is vast. I have a bunch of 740 and 2000 archives. And even with all these reasons, I still kept searching and searching...until I finally made up my mind to BUY SOMETHING!!! Not to mention that I'll probably go through this exercise the rest of my playing life (thank God!) For now, I'm seeking a Pro.
