I found http://www.stompin-ground.com on the web, and liked the looks of their stuff. For flight cases, they're pretty cheap, and they're happy to build custom sizes and configurations. I'm getting ready to order one 32X60X7 for my drum machines. I just got another one from http://www.musictoyz.com/stdboard.htm and it's OK. The price was good, but it's not built exactly the way I would have done it. Definitely better than a milk crate, though.
