[OT] Looking for hardware?

I’ve built a small box to learn asterisk on. My $1M question (which I am sorry, I know is horribly off topic, didn’t see a “shoot the breeze forum”) is “does anyone know of a good place to barter for equipment?” I have tons of junk, which I’m sure my wife would like to see go away- since this is really a hobby, I don’t want to shell out the 249 for a Cisco 7940. I’d be willing to trade a good deal of “junk” for it though.

Any such forum exist?
