The crown has only been out for a few weeks in UK, chance of finding a second hand one is more than a long shot. Also it only comes in 2 sizes, normal and large, I have brought the large, seems a very good pack but I havn't really tried it yet.
good luck though
The vapour trail has been discontinued, however ultralight do have one left in short torso, if your willing to pay full price for a new one you might want to snap it up.
