If you're near a Sam Ash store, stop in and try their 1164B keyboard bag. They also have some semi rigid cases similar to Guardian. Their house brand is Groove Pak. http://www.samash.com/webapp/wcs/stores/...ategorySA182981
Otherwise I agree with Donny that Guardian is a good choice. Double check Gator tho, they might have an alternate bag/case than the one you've seen or used.
