Here is the latest keyboard case/bag I have purchased..
I originally bought the slim 76 model but the BK9 was a bit too tight (did not fit).
I returned it for the same model but standard size.. The BK9 fit with a little extra room, and the G70 fit perfect... so I could use it for either keyboard..
It weighs less than 10 pounds, and maybe the best made keyboard bag..
My G70 in my other Gator case weighs 20 pounds more than in this new Gator bag..
