Go down to your local cheap sporting goods store and by a golf bag case. They are inexpensive when on sale and should fit your KN7000. I bought one for my KN6500 on sale for $39.95 and fits with room to spare. It also has wheels on it. Then all you need to do is get some foam and cut it out to fit the bag and your instrument. This makes for a cheap, sturdy, easy to handle case. The wheels really come in handy! Also, has pouches in it to carry other things.
