I bought the Road Runner RK5414 Keyboard Bag because I needed a rather inexpensive bag for my band's backup keyboard, a Casio PX-310, not a heavy keyboard by any means. The 4th rime we carried this bag by the handle the bag ripped at the seams on both sides. Not quality constuction or material by any means. I wanted a cheap bag and I got one

I bought this recently for my Roland RD 150 and the length is perfect. It's a couple inches wider than my keyboard so there's enough room to pack in some accessories. The pedal and a patch cord fit in the pocket. The strap and handle seem to be well attached--reinforced stitching and cast metal grommets. The Roland weighs about 50 lb and I'm not worried about dropping it. Padding is a bit thin. I wouldn't stack anything on top of it or check it as luggage, but for carrying my keyboard in the back of my car, it's just what I need.
