assume you are going this route on a cost basis, and, not knowing that,
it's hard to give an informed response...

....that said, some things to consider in addition to general condition
issues;

are os restore cd's available? if not, and if they are not available
from motion, you may be stuck with a brick if you need to reload the os

screen condition

pens included? (how many)

buttons all functional


as far at the "keyboard/stand" any usb keyboard should work plus, if it
does not have bluetooth built in, you can add a bluetooth dongle and use
bluetooth kb/mice
