I have two used David Clark headsets (H10-30 and H10-40), each with separate push-to-talk switches. The ear cusions need replacement but otherwise they are in good shape.
I am in the Portland, OR area if you want to see them. I have seen prices between $75-$85.

I have an ICOM IC-A21 that I no longer use. Have not used it for about 10 years but it still works. I also have the 120V and 12V chargers and antenna cable.
I live in Portland, OR. I do not know how much to ask but I have seen prices around $150. Let me know if you are interested and I will try...
