I don't lug around a Super Canvas for the few sounds from my G1000 that aren't in the G70! When I move on, I move ON...

Let's face it, if you are THAT big a fan of the Ketron sound, you are going to want a REAL Ketron Audya, not the stripped down module of an SD5. Might as well get a V-Machine, and MIDI it to an Audya if you want a few GIGA size RH sounds...
It would be a bloody site faster to get a decent sound together that way, from all I've read and heard!
