High asking price, but at present it's just that, no bid, and not bought. (original link).

The truckload of sets in central PA with the monitor cabs (last year?), went for a mint. Would be good for comparison.

I sold a single, nice 515B, along with a single multicell, 288, and some XO's not too long ago, for the princely sum of $~600 iirc.
Hah. Guess I should have paid for that storage after all.
