I've got two Phase One P21+ digital backs up for sale. These were all used/maintained at our professional photo studio and are in great condition. These are all H-mount backs and come with 2 batteries and the charger, no cases. EDIT : The P25+'s and the P21 have been sold. The P21+'s are the only ones left.
Two P21+: This is also 18MP 16bit but it shoots faster than P21. 1.25fps vs 1fps. The rear LCD also has double the pixels.
Price: $4600 USD each shipped within the US. Outside of the US add $50 for shipping.
Serial#'s: DV000166, DV000169
