WWW aviation classifieds

[Jackie]

Hi there, I'm wondering if there are any popular aviation-related classified
forums on the Web that are devoted to selling aviation gear? Not aircraft,
but rather gear such as headsets, transceivers, instruments and the like? I
did some checking around and didn't see anything but sites for selling and
buying aircraft. My boyfriend has some decent aviation gear he would like to
sell (he's no longer a pilot) and wondered if there was anywhere he might
get some bites on it besides eBay.

Thanks!

Jackie
