Already up to 47? Wow... not that I blame you, if I had the disposable income for it, I might do the same. I should be up to about 12 by the weekend, which I think is enough P1 clones for me.
I'm not so sure that Hasbro's going to do a good job with the P2 helmet though, the pic of the Vintage 501st one has me nervous, it just doesn't look as good as the helmet from the ROTS #41 clone.
I might try and get about 10 more of the new mold P1 version, and put that older helmet on it. Might be a pain to do since the knob won't fit naturally (yes, I know how that sounds), but I think I have an idea that will work.
