I still feel, once you get up into the $3000+ keyboard arranger range, especially as, if damaged they may not be so quick to find a new one to replace, a hard case of some sort is still a good bet, despite the slight weight increase. With many of them having wheels at one end, you still end up rarely ever toting them.

But assuming that your so far accident free life will continue that way is quite a gamble when you consider the inconvenience and possible disruption to your usual gig setup.

The more sliders and knobs, the more that dropping something on top of it can do permanent damage goes up. And don't even get me STARTED about how impossible it is to work an arranger like the PA3X if the touch screen gets cracked!

Better safe than sorry, I have always said.
