Our local Best Buy has an electronics drop-off, and the city has a couple around town. It's PC to be green around here, so there are several E-waste disposal opportunities.
Used AVRs, re-purposed speakers, and TVs usually are given away to guys in other trades who we work with pretty regularly.
I came into this game for the action, the excitement. Go anywhere, travel light, get in, get out, wherever there's AV trouble, a man alone.
