I currently own a PSR-630. I'm quite satisfied with it, and it has served me well (yes, I gig with it, despite the fact that it is not a "professional" keyboard). When the 640/740 came out I was not impressed enough to upgrade, but the 2000 looks like a winner. I haven't had the opportunity to try one out yet (no local stores carry it yet), so I'd like to ask a few questions of the 2000 owners.

1) How does the quality of the panel sounds in general compare to the 630? The guitars in particular certainly leave room for improvement.

2) How does the quality of the styles compare to the 630? I know there are four variations as opposed to two. How live-sounding are the styles?

3) Can an XLR mic be used with the 2000?

4) How road-worthy is the construction of the 2000?

5) Is the AC adapter finally included with the keyboard? I thought I read this somewhere on Yamaha's site, but I can't seem to find it anymore.

Thanks for your help.
