Looking for a high end analog mixer and was wondering if anyone has experience with these brands. I've had my eye on the Mastersounds Radius 4v, but they are a smaller, newer company, so I'm not sure about customer service, build quality, etc.
Formula Sound and Bozak are both pretty well established companies so I'm a little less worried about purchasing from them.

The Bozak has a separate EQ unit, so that bumps the price up significantly, so I'm thinking I may be deciding between the MasterSounds Radius 4v and the Formula Sound FF4.2R or FF6.2R.

Any info anyone may have would be appreciated.
Thanks!
