I don't know the demensions of a TYROS but have any of you ever looked into a golf club travel bag? I have one that fits the kn6000 pretty well, and while the bag is obviously not designed for this, it has suited my purpose, especially since like some of you, I'm the ONLY person to handle the kb ... padded, wheels, and a lot less money ...
