I have an Autek WM-1 and it is a nice meter, but it's accuracy degenerates 
very quickly below 10W. This is not uncommon for Wattmeters that are not 
specifically designed for low power (could well be the case for the Palstar 
meter). A good inexpensive QRP Wattmeter is the OHR WM-2; it has good 
accuracy down to about 25 mW or so. Full scale selections are 100mW, 1W and 
10W. There is an easy "peak reading" mod posted on the ARCI web site; 
www.qrparci.org -- look for the "Technical/Projects" link).
