Best deal I have ever seen was in the local Austin-Statesman paper. A doctor I assume by his email address was selling a stereo system package of QSC 500W amps and a QSC preamp, Magnum-Dynalab tuner and a pair of passive ATC SCM300's for $2600 obo. Lets see the tuner retailed new for ~3K and I would guess the QSC stuff would cost a couple of thousand new as well, so the asking price was a decent price just for the electronics.
The real kicker is the speakers as new ATC SCM300's cost close to $30K and if they had been the active version they cost over $50K. There was a pair of passive ATC SCM200's on Audiogon at the time listed for $12K and the 200's cost almost half the price of the 300's. Unreal deal, that I was unable to jump on because I had just bought a $4000 preamp, so no excess cash to swing. It pains me whenever I think about it, as you could of probably easily turned around and sold all that stuff on Audiogon for $15K.
I saw a similar scam a few days ago. Some guy with no feedback was offering 3 sets of new, in-the-box, top-of-the-line, Martin Logan Prodigy speakers with no reserve. I checked the next day and the offer was gone. I suspect he was caught.
