I use this to hold/transport a Soundcraft MFXi 12. The case feels well made, and the rails are stiff enough to support the mixer without risk of it lowering back down under the weight. This is at the cheaper end of the 'Thon case' range, however the workmanship remains of the same high standard. The only real difference is slightly lighter materials all round. Thinner wood, smaller corner braces, less tough looking rivets. Easily robust enough though, no danger of damage coming to it's contents.
Good case - especially at the price!
