Thon Keyboard Case Tyros 5/76 PVC

I've ordered the PVC over the wooden one mostly because of slightly lower weight, and expected some compromise on the protection, but I can tell you that the PVC panels are more than capable of keeping your keyboard completely safe in everyday situations, even taking decent direct hits during handling without any problems at all.
Internal foam padding is sufficient as well. Although it's specially made for Tyros 5 76 keys, I had to trim the foam on the top front part at a slight angle in the corners because the foams where pressing too hard on the keyboard, and I couldn't close it. I think it may fit other keyboards as well, if you fit in that measurements.
Locks close the case with assuring click and they won't open by itself anytime soon. If you fly with your instrument, you can also put a padlock on the middle lock, so you don't have to worry about deliberate damages by someone opening the case whenever you're not around it.
The side handles are punch riveted on what looks like to be a honeycomb PVC panels, without additional reinforcement from the inside, which is probably not the ideal way of doing it, but...the time will tell if I had the reason to worry about that. The top handle is riveted to the aluminium bars, and it's strong enough to carry all the load without any problems.

Pros:
Well build. Reasonably prised. Not that heavy for it's size and materials used. 2 side handles + 1 top one

Cons:
A bit awkward to carry for a single person by the two side handles, but it's very comfortable for 2 people to do so. I'd liked it even more if the side handles where holding the rivets on a metal flange inside as well, instead on the plastic sides alone as they carry all the load.

In general, it is a very capable and strong case that probably would last many years, if you're not being totally negligible with it.
And just for convenience, a version of that case with wheels and one handle to drag it along, would have been a nice alternative for weight of a keyboard+case that surpasses 25 kg.
