I've used an older 8x4 quantum console for tracking, the pres are pretty usable on drums in particular.
FWIW, that same studio now has a 16x8 quantum console AND a Yamaha PM 1000. While I haven't been back since either of these arrived I know the owners can't decide which sounds better. Keep in mind the Quantum they have is an older board than the one on ebay. Who knows what condition the caps etc. are in.
I know tiny telephone in SF had a large Quantum console before they got their Neve-- if you have the tape op book it's in there somewhere.
I wouldn't write it off, but at that price who knows.
