I've been trying to find a hard case for my X3 Live, but any kind of gear accessory case is either to big, like for a keyboard or mixer, or too small like for mics or something.

there is a soft case that line 6 makes, but i need somethin with a little more durability. any ideas?

I think you'll have to look for a ata flight case for a pedal board. If you have dimensions it would be easier to find what you need but from the pictures I believe that your pod should fit in that case, but it's really expensive if you ask me.
