For the past few years, I've survived by having all my measurement kit in my gig bag.
I've a nice little peli case for my mic, but the soundcard just gets a brutal life.
I've recently added a PC tablet to my kit and my back and gig back are straining at the seems.
Ideally I'd want a case that is 'plug-and-play' rather than secure transport, but at this moment, just a peli case and pick foam is appealing.
Final thing is it needs to be Airline/baggage handler proof!
I was interested to see how everyone is transporting their systems?
