[Elecraft] Decoder for use with K3 and PW-1

[K4GM-George]

I'm looking for a decoder to use with my K3/PW-1.    I realize there are 
several options available but would like input from someone actually 
using one before I buy.  The PW-1 has sat unused since I bought my K3. 
Now that I have the bias mod installed I'm ready to focus on either 
using or selling the PW-1. My L4B works so well and doesn't need to go 
to the shop every time I accidentally hit the remote head or the 
outboard tuner arcs.  All comments appreciated.
