Bagged a very nice Harry Potter haul off eBay that arrived this weekend. Every set from the 2010 + 2011 waves apart from the promos, all in one jumbled lot. I paid about £350, and it comes with all instructions and all minifigures (checked). I estimate it's probably worth about £900, so a good buy!
The same day that arrived, I also got these: A Town Hall (10224) and Detective's Office (10246). They were shipped built (strangely) but that means I can see that barring a possible couple of very minor pieces they are complete. No instructions but I paid £200 for both (eBay again), so can't complain! Sorry for the photo quality, my phone refused to focus properly.
