You want N8LP's excellent LP-100A. I had lusted after one for quite a 
while, and bought W6OSP's unit after he died for about half price. The 
LP-100A supports two couplers, which can be deployed on the outputs of 
both transmitters in an SO2R setup, or on input and output of a power 
amp. The LP-100A measures the complex Z at the coupler, so it can 
measure the input Z of the amplifier under dynamic conditions.

Now that I can measure power more accurately, I am able to run a dB or 
more closer to legal limit when I want to for contesting.
