Russ as for bags/cases..I have a Gator 76 w/wheels I use, and just bought a GigSkinz 76/w/wheels[because it is 12 pounds lighter than the Gator..The Gator gives superior protection..The GigSkinz is designed to be lighter..more like a heavy padded bag with wheels[with the G70 it supports well, but a plastic keyboard I would have concerns wheeling it]..There is no inter-structure to the bag other than padding..

I wanted a good padded bag for lighter travel and the GigSkinz is exactly that, and I have the option to wheel it if I want..It may be available for sale[$150, never used..1 week old]..List is $299..
