How about a Berlebach?
Actually, I have the Bogen 3020 and the 3047 head and it works very well. The 3020 is more moderate in the heft department, but my MF and LF rigs work great on it. It is more than enough for the Mamiya.
My wife is impressed, otherwise, not too many females have commented. The guys, however, seem to really be impressed with it. Maybe there is a little tripod envy going on.
