Saw this today. Don't need another receiver, don't know if it works, but I thought someone else might like to know about it. (Goodwill at the intersection of El Camino Way and E Meadow).

UPDATE:

They had some Paradigm mini towers, too. Looked a little beat up, but I didn't bother to take the grills off (they're too big for me). Someone could grab these and the Kenwood above and have something decent for under $100, if everything's working.

I might swing back again tomorrow and take a closer look to report back here, but don't count on it!
