Another good one is the WaveNode WN-2. www.wavenode.com

I have one in the shack, it shows fwd and reverse pwr, Is very accurate. also 
the software to have a display on the pc is nice to wow visitors (and yourself) 
from time to time.

  Elecraft W2 that I have is a nice toy to give flashing lights to the shack, 
but very frustrating to use to try to peak up a linear amp. The gradients of 
the bars in the bar graph are just not fine enuf to do the final adjustimet to 
an amp.  Skip this one.   I use the WM-1 from autek and it is also satisfyingly 
old fashioned looking, has both peak and incident readings.  73
