Time to scrape together the money for one of these!
I believe BM is also going to do a "detail only" kit that does not include the body pieces, just the detail parts.

Ugly little beast! Of course, beauty is in the eye of the beholder! I think this kit is a nice option for those who wanted a more "traditional" Heisler in terms of appearance.
