Very tempting. It all depends on the quality of the lens shims so one can rely on the distance set on the lens. That one can check. Once it is set, there should be no issue at all. That's the critical thing for me.
Weight is already provided. How it balances in the hand, view finder and practical use of a ground glass screen are secondary but practical points that only someone using it can tell us. I like the fact that it's inexpensive and simple.
