I have a monk in my collection, I built it up to see how it looked but put it back in its box. It came with it's instruction sheet and whit mailer box that was sadly a little creased in the post due to being sent wrapped in brown paper by the idiot seller who I bought it off. I think I paid around £5-£9 area for the monk, but they can range from £9 to £15. They aren't really massively rare but not seen to often in the box with instruction sheet.
I think it was an internet exclusive....cool figure though, a must for any POFT2 collection.
