I'll lose a little sleep over the Gree and Malak Busts - only because I know they'll cost $100 each later on. I'm also a little concerned about the Japanese and UK Clone Busts, so multiple Gree busts would help me not lose as much sleep over those.
The Hasbro thing, depending on what it is, I'm not worried about. Talking Vader just takes up space as far as I'm concerned. if they actually make something cool on the other hand...
I always look at Con exclusives a little differently I guess. If I were going, what would a one day pass cost? What would a four day pass cost? How much is my time worth to stand in line for four hours before the doors open so I can run in and stand in another line to see guys that weren't in the line and miraculously seem to be in front of me now? $100 for a Con exclusive doesn't bother me a single bit to be completely honest. I'm all for paying $55-60 instead of course, but I can justify the other costs pretty easily.
As for the Japan/England exclusives, well, I have a shot at the one from Japan thanks to a friend there, but the one from England I'm hooped on. I'm just not obsessed about being a completeist with anything, anymore. I want 'em all, but I'm not about to obsess (he says now, knowing he'll eat his words later).
