I got my Cobra 200GTL-DX from them, asked them what revision the board was, the assured me it was the latest, and based on the serial numbers, they're right... version 3... radio hasn't given me any trouble.
At the time I decided to buy it, they were one of the few dealers that had one left (Cobra has ceased production... after finally getting it "right").
Good, fast service. And yes they did the "tune up", again, no issues, works great. Guess it depends on the tech you get, they must have more than one.
