I am a stagehand, and I have seen what happens when people make there own road cases (or use SKB crap). It is NOT worth it. If you are going to do any significant travel (even in town) you need to get good cases. Anvil would be a good choice, nothing less. You spend a lot of money on your gear, and unless you have access to a major woodworking shop, don't do it. I have access to an amazing shop (my father is a guitar builder), and I still would not do it. Besides, if you use an Anvil, your insurance is much more likely to cover you when you travel. I looked at the case in the link, and it was not good. Real cases need edge and corner protection, and a rugged covering. I know I am being overly wordy, but please, trust me. I know what can happen, and that it is always the stagehands who get blamed, and it is not our fault if you use a crappy case.
