Clay,
An LP-100A calibrated to N8LP's NIST traceable standards is about the
best you are going to find at a price that is palatable to most hams.
Used in conjunction with a precision 50 ohm dummy load, the calibration
results will be better than most other wattmeters.
The LP-100A. I have one at the workbench that serves as the secondary
standard for all my other wattmeters. With NIST tracable calibration
it's accuracy is typically 3% of the reading.
The Elecraft W2 is also good for that task and should be sufficiently
accurate with its +/- 0.5dB Accuracy specification.

Would the LP-100A meet the accuracy/precision requirements to do the
power cals outlined in the K3s Manual?
If not, please supply recommendation for one that will do the job
adequately.
