To Beaky Bird,
I just bought a psr-s900, and am loving it. The case that you mentioned at the top of the page (the Guardian Featherweight 61 keys), Before I buy one, Are you a hundred percent sure that it fits the s900? No problems? (I'll need to take it on a plane a few times).

P.S. I'm happy that I didn't get the Tyros2, I don't see it worthy worthy enough to cost the extra $1800 or so! Thanks for the suggestion.
