Gator TSA 88

Got this to protect my Roland FP90x - fits perfectly, adapter pieces fill up empty spaces. It's built like a tank, and it's supposed to be as TSA series product.
It handles like one too: you need some space to store this when not using it. You can't remove the lid to leave the bottom as playing bed, so you're stuck with a coffin you gotta hide to avoid people reporting you to the local police. If you want to be sure your EP won't get damaged, get this.
