I bought the Haunted Crypt for about $100 off eBay which was not too bad. I believe it was $70 at the con. I need most of those T2 variants too, except for the Hole in the Head T1000 which I found at TRU yesterday.
The real bear for me is that Haunted House Playset. Apprarently they only made about 10 of those because there are very, very few on eBay and they are all ridiculously priced compared to the other exclusives. I think I'm going to have to wait that one out and hope I get lucky down the line somewhere.
