For some reason the saber errors don't bug me as much as blaster errors... I think it's mainly the similarity in the sabers, whereas the blasters are vastly different. But if one wanted to, I was just thinking how you could point out accessory mistakes throughout the line really...
V30AC Hoth Han's gun is wrong...
V30AC Leia Endor's gun is wrong...
30AC Luke Ceremony, wrong...
That's just off the top of my head too, I'm sure there's many more.
To be honest about the LUke, I don't mind it much... I'm sure with a better deco, the headsculpt wouldn't look bad. To me, it's one of those figures that is a diamond in the rough. The pale skin and beedie eyes are what's killing him though. Definitely not the best work. I still place Tatooine Luke as a much worse figure overall, but the coloring on Ceremony LUke does bring the figure down a notch. Better though than his predecessor, and a good toy, just a bad figure for realism, that's for certain.
The pistol still annoys me, however I got a V30AC Leia in the order I placed with Hasbro not long ago, so I'm transplanting guns and she's going to be my "Briefing" Leia replacement I think.
