Don't forget to rate them against each other in respect to optical
quality too....don't have experience with the Arsat/Mir, but I am not 
100% convinced that the RB is optically king of the hill...

That's what I did....ordered a body-mount, assuming/being-told that
the one on the tube was identical....they are slightly different
though, the tube-version is a full circle on the outside, the
body-version has a slight straight part....doesn't affect mounting
though. Don't forget to order the screws too, and check screw-thread
taps in size M2.5, to tap the matching holes in the lens
board (once got a Graphic board along with a camera, with a large
diameter opening, almost made for it, only had to drill & tap the 
screw holes....surprising match).
