CB Performance Air/Fuel meter?, Who's used it, and with what kind of results?? Options

Hey Gang,
I've been eyeballing the CB Performance Air/Fuel meter to assist in dialing my carbs in. My eye is not well-trained enough to do it by looking at the spark plugs, so I though an A/F gauge might do the trick. It's about $130 for a three-wire heated O2 sensor, gauge, and exhaust bung. Anybody used it? Any others I should be looking at? I'd consider the Innovate unit, but it's over $300, and until I megasquirt, I don't think logging data will be that useful for my street only car. Also, as the car has dual carbs, would it be a good idea to weld in two bungs(or even four) so that I could switch between cylinder banks, or even individual cylinders? My thought is to mount the gauge in my existing clock (non-working) hole in the console. Any advice related to A/F meters and carbs is welcomed... Thanks!!

I have one in my race car and an O2 sensor on each stinger. I switch them back and forth on a race weekend to see what the O2 reading at full throttle is as that is the only place I really worry about it. If I am on a clockwise track like Willow Springs it plugs onto one side and at the CCW tracke like the CA Speedway, it plugs onto the other due to float movement of the Webers on lond turns.
