I think that much of the appeal of a Bridgestone is the quirky assortment of components that came on them. Bullmoose stems, bi-plane fork, Deerhead derailleurs, etc. Without those things, I suspect the frames will go for a bit more than an otherwise comparable one.
I have a MB-1 myself and am thinking about selling it this summer, so I am curious to see what you get.
