We went hopping around a few thrift stores, antique malls, and indoor flea market type businesses today. I'm not sure why I did it, but I got on all fours and looked in the bottom shelf in a seller's area. I saw a hunk of black metal that felt heavy enough to be lead. It was tagged $20. When I got rang up, I found out it was 50% off, so I got a nice 100 watt speaker for ten bucks.
