I use a high stool and a Quiklok M91 keyboard stand (thanks for the idea Scott-same width on the floor regardless of height) because I play a lot of stuff out of fakebooks and I'm always glancing at the music, it makes sense to me-to keep my head at just about the same angle-when I'm looking at the music (esp when I'm playing a solo)or the crowd. I just keep working at it and hope someday to be able to raise the M91 stand a bit more and get rid of the stool.
