I would pay $9000 for MM, $6000 for MB, $6000 for AFM and $4500 for CV
Those would be considered realistic but GOOD deals if 100% working and not too bad for routed games. In other words, there is BIG spectrum for a 'routed' game and I am referring to ones that are decent and at least maintained/working properly.
Both MM and AFM in good but routed condition seem to be selling a bit higher than the above prices. A routed core machine MM sold on epay for 10k not too long ago. A routed core AFM sold for $6500.
A piece of crap beat up MB sold local to me for $5800 recently. CV I do not seem to see as often.
JMHO of course
