I was looking for a wide-angle lens and the 55mm seems to fit the bill. I'm not trying to be a bokeh freak or anything, but I really dislike harsh bokeh, and the Mamiya 7 is known for that.

I was wondering if the 55mm on the TLR shared a similar reputation; if it did then I'd opt for a 645 camera like the ones offered from Mamiya, Pentax, Bronica, or maybe even Fuji. The 55mm on this camera seems worthwhile; although a bit slower than the 645 SLR's.
