I have a similar situation.
I've been thinking about buying the 1st version (an EX in the aftermarket) for awhile now, even after I got the She Devil with a Sword EX in hand. However, the 3rd version has me hesitating because now I'm thinking maybe getting that would be better than getting the 1st version. With the 1st version, I'd have to get it repainted. And that's going to cost more than if I just buy the 3rd version. I still love the sculpt on the 1st version, but perhaps its time to pass on it completely.
