I won't to point out that not all watt meters are created equal. Most
inexpensive watt meters only monitor RF voltage. They are calibrated
assuming the load is 50 ohms. This is only the case for a perfect 1:1
SWR. More expensive meters like the LP-100A have both current and
voltage sensors and read correctly for all loads, not just 50 ohms.

That only matters if you're a cheerleader. If you're an objective
observer, and want the best bang for the buck on a really good
wattmeter, look at N8LP's LP100A. Elecraft uses them on the production
line to test their radios. I've got an order in for his new one, the
LP-500, which can display the output of four SWR couplers. The LP100A
has been around for years, and is a mature product. The LP500 has not
yet shipped.
