 they all can be expensive. 
I just brought home two of the rare P75's (aka 8573-161) yesterday.  I'm
willing to trade one of them away for something equally as rare and
interesting.  These are nice usable vintage boxen.  I think the 8573 was
intro'd in 1990 (OK, not quite 10 years old), has a gas plasma display,
built-in SCSI, and two full-length + 2 1/2-length MCA slots.  I think they
sold for close to $10K when new, which explains their rarity.
