what are your top "audio bargins" in your system history?

I paid a dollar for about as mint as it gets of Beethoven's nine symphonies, Karajan/ Berlin on a tulip bordered Deutsche Grammophon box set, most sides not even a pop on them.

$40.00 for an unopened box set of the 58-65 Solti / Vienna Wagner Ring.  I have only seen two sets, one nice condition, the other acceptable, and any other set, trashed.  I almost wet my pants when I saw it, an unopened box as I wasn't even shopping for music.

I wonder if the SL600's I donated to the local thrift store ever found an appreciative home. I wonder, too, how long the tweeters lasted, or if the new owner even gave a damn.
