I'm with you guys on the cleaning issue. I keep my board under a dust cover at all times. It also sits on a stand with rubber caps for protection underneath the board. I clean it weekly by vacuum, and slightly damp cloth. Like Gary I also use canned air to blow out speaker grills, between keys, and underneath them. Dust is the WORST enemy for a keyboard. It can really mess things up.
