Howdy!
I would definately consider what my anticipated use of a case is, 'cause you never know when you will have to trust it under a plane.
I personally looked into some industrial sites and found that the company Pelican has some crushproof, waterproof, dustproof (even with a pressure release valve) cases but they are around $300 (and up!). They do have one I was looking at,with wheels and an extendable handle that will hold the DPS and your burner and your cables and your mics and you can cut the included foam to your own specs.
Again, it depends on where you see yourself going. Of course, a good case is like car insurance...you hope you never need it, but one time when it works well is well worth it!
Another place called Star quoted me on a custom built job for around $350. I am now considering having them or someone build me a deal with a hinged back so I will never have to take it out of the case.
