On the Oostendorp cases. It's interesting in that they look basically identical to the Gaurdian cases. The Gaurdian cases cost a lot less money. I'm thinking maybe the case from Poland was imported from China where the Guardians come from. But, again, the 61 is too short and the 76 too long. I really wish Yamaha would contract with the Gaurdian case company. It's interesting to note that the Guardian 61 and the Oostendorp case both weigh(ed) 13 lbs.
