I think the 2000 will hold up to the way I play. Having never been a piano player, I realize that banging the keys harder does not produce louder sound as it does on a piano. At least after the touch sensitivity point is reached.
I learned this lesson many years ago by having to replace all the key mechanism on a Lowry organ. Big Bucks.
There was a really great piano player here some years ago. (He's now in Las Vegas). I finally barred him from playing my keyboards simply because he would get so into the song that he would physically break the keys.
I always use stereo, mostly for my own enjoyment.
Uncle Dave and I are much alike in caring for our vocal cords. Don't strain. Alcohol is bad for you, not only for what it does physically, but it can make you lose control and start screaming. Also, it makes you THINK you sound better, when it generally has the opposite effect.
The second-hand smoke has long been one of my pet peeves. That's the great part of working in the Nursing Homes.
I gnerally drink warm beverages before the gig, and water or juice during.
There are generally several "guest" vocalists who are more than willing to do the screaming type songs. Incidentally, the compressor/limiter in the PSR's is great for these guys/girls!
