^^ While everyone and their mother makes square taper BBs, its important to remember that JIS cranks will bottom out on ISO taper BBs; conversely, ISO cranks sit too far out on JIS BBs. If the op goes with Miche, I'd suggest forking over additional cash for a Campy BB; very, very high quality ISO BBs.
The wise choice is to avoid ISO altogether. Very few manufacturers use ISO, outside of grandfathered Campy, Miche, and some NJS stuff. The rest of the world is using JIS or has switched to external bearing systems or ISIS/Octalink.
