My latest addition is the MK-7. The uke cost 70 bucks. I am not going to buy a 25 dollar case for it. The cardboard case fits it pretty perfectly, so what I did was hinged the top to the bottom of the carboard and encapsulated the whole thing in duct tape! Thing is that this case stands on its side or on its end pretty perfectly! I have yet to enhance it fully, but my wife tells me that you can get colored duct tape... and I am now having visions of my new Black Hard Case!.... don't know if anyone else has done this yet.....
