Thinking of an air-fuel meter to tune carb - any experience?

I use a LM 1 as well. I use bungs welded into the exhaust pipe at the front of the collector. If you mount the bung towards the inside of the car there is no need to re-coat the pipe as it cannot be seen except from under the car. The LM 1 will do a much better job than an ear ever will. Well worth the money.

If I get the LM-2 with an exhaust clamp, I can use it on multiple cars, on both sides of the exhaust, and without removing the sidepipes to weld in a bung. Can you drive with the exhaust clamp, or only use it while parked?

Yes, make SURE you mount it somewhere on the collector as ANY exhaust leak with throw the readings off, ask me how I know.

I've got an LM1 on a twin turbo truck, and I mounted it just after the collector as the headers were already in the truck.

Well, even with a V-band exhaust clamp I still have a very slight leak which drives the AF gauge wild. So guess what I will have to do all over again.............

This review by Ford Muscle confirmed to me the LM-1 and LM-2 are the best choice.

I use an AEM. It mounts in the dash and reads vacuum and AF ratio. It data logs 3 hours of data and plugs into your computer so you can down load and evaluate the data. I have dual quada and it has helped a lot getting things dialed in.
