WTB: Looking for a few Harry Potter sets

Specifically looking for the Durmstrang Ship (#4768) and either of the Hogwarts sets (#4709 or #4842), but open to any other HP sets (except the Burrow - thanks @indigobox). I want to build these, so I am happy with used sets as long as they are mostly complete.

Please shoot me a PM if you have any Harry Potter sets available!

Thanks - PB
