I am "entirely new" though, so all I've accumulated so far is the three Alien Appendices, Deleted Magic, Building Emp, Returning to Jedi, Supes Redeemed, Twilight Zone TM, Monster Squad, and I just got the TV cut of Needful Things. (But the 2nd disc seems to be corrupt. Bugger. He already did me a favour, so I'm loathe to mention it.)
If Meedermow hasn't already sent off a copy of App.3, let me know...I'll be happy to throw one in the post for you.
