[Leica] three questions: C41 b/w film; Mamiya DM22; why no US version of GF1 w 20mm kit?

[passaro.vince at gmail.com (Vince Passaro)]

I'm contemplating C41 b and w film. I've used the Kodak and liked it
sometimes and not others (dependong on factors I was too ignorant to learn
how to control at the time, I suspect). My impression though was that Koday
was the best of them but I do recollect an Ilford that some people liked...
perhaps it was that 50 ASA of theirs?

Anyone using C41 and feel knowledgeable and opinionated enough to declare
differences and preferences?

Or, here's another question:

I see on B&H site that there's a Mamiya medium format digital camera for
under $10K, called the DM22. Anyone know about it, have an opinon, etc? for
the price it comes with an 80mm lens, which I guess is kind of an equivalent
to normal size lens?

And finally: among you GF1 fanatics out there -- does anyone know why you
can buy the GF! with the 20mm as a kit in Europe but, after a brief
availablility, not here? (here being the good ole' US of A folks. TGeam
America. Burn the camera in order to save it. Semper Fi. all that.)_

Thanks
