Well, it is for me, so I'll pass it along. If you have a Lowes home improvement store in your area, they carry a tool box that is black, with a red lid made by Contico. All I had to do is screw in two 1x3's to hold the monorail. You can scr ew in dividers, line it with foam, sit on it because the lid is so reinforced. I t fits my Calumet 45NX perfectly. $22.00! The Tenba Air View ($250.00) is now co llecting cob webs. Its monsterous compared to the Contico. By the way, this same company makes an attache style aluminum case. I didn't check it out. Don't know the quality, but I think it was $25.00. On ebay, someone was selling one for ph oto equipment.
