I definitely want an LP100A, but I HAVE a W2, and while it is not as
accurate, I still would like to see the delivered power!

that is, forward power minus reflected power.
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.
