[Elecraft] K3 Assembly Question

[Dave, W8OV]

I'm considering ordering a K3 kit soon.  I wonder how 'optional' these 
items listed in the assembly manual really are:

Optional Equipment:
1.  RF Power Meter with accurate readout from 1 mW to 5 watts, minimum.
2.  Signal generator with calibrated 50 uV output at 20 or 40 meters. 

I have a Bird 43 wattmeter, but don't know of any element in the HF 
range that would read 1 mW.
