I sell the Gator GK61 case Jon is recommending. It is the 61 key version of his GK76 (76 key version). It is very strong, good wheels and handle and it has two velcro straps inside the case to hold down the keyboard when transporting. It also has hard plastic runners on the bottom of the case to help when pulling up stairs so as to not rip or scratch the case. The price for this case is $99.00. I have them in stock.
