Been debating this for a long while with myself. I got a reissue G1 Screamer a time back, was probably the first figure I bought since...a long time. It basically got me back into collecting (though it wasn't until the movie line that I bought any new figures >_>..so was a couple years between 'em). It is MISB, and I do like the way it looks all nice and sealed..however, I've been really thinking about letting him out and just transforming him (never owned a G1 SS before, only G1 figure I had was a grimlock I got many years ago [long since gone]), then reboxing him and leaving him MIB on my shelf. I know that once open it can never again be MISB, but just...oh so tempting to play around with him a bit. So consider this a semi poll of sorts.
