I had picked up an Angstrom case, as well, although it's not the same style as Lone Star States or Dann'sTheMan's. I got the one with the extra storage for extra tubes or cables. No wheels. Yeah, it's bigger, but I have a pickup, so the extra size isn't a problem. I picked it up in the 3/8" ply, so it's pretty solid. The extra width allows me to put other stuff on, so it's in reach and off the floor. I figure that I can always get a two wheeled cart, if I need to tackle a set of stairs.
Nice cases. They also double nicely as an amp stand and help get your rig off the floor if your not using a 4x12.
