What Intuos is it i.e. 2 or 3? Also if you do make the trip test it out and double check the cord at the point of entry into the tablet. Would this just be the tablet or does it come with the pen? Hey if it works well and is an Intuos2 or 3 then I'd say it's worth it (more so the Intuos3). It's obviously going to be quite large but if all goes well I posted a Wacom Tablet Setup (something like that) in the help section here on MR so you can scale the usable tablet area down if you find you need to put to much (excuse the pun) elbow into it
So sure, good shape, no chips or cracks and the cord is in good shape, sounds pretty nice
