As I stare at my DVD collection, it's kinda sad that all my unfinished collections include volumes that are VERY hard to find in stores nowadays (at least for me they don't really re-order them). So not counting anime that isn't even licenesed yet (like the 4th Inuyasha movie to add to the rest of your stuff), and not including collections you haven't started yet, what do you have to add?
I'm missing...
RahXephon vol. 4, 6, 7
Chobits vol. 6, 7
Haibane Renmei vol. 1, 3
Magic Knight Rayearth boxset 2 (only had enough to get the first one v_v)
Inuyasha boxset 2+ (only have the first set and the first 3 movies)
Luckily for me, I got the chance to finish my .hack//SIGNs and Angelic Layer sets recently^^
