Another vote for Tony Rose at PopFlash. Outstanding service and he seems like an all-around nice guy.
re: grey market stuff. My impression of grey market has always been that the only difference between grey market and "official" gear is that the non-grey market stuff has been simply marked up by local distributors to factor in their take of the overall selling price, with the benefit that Leica (or Nikon or Canon, etc.) will only honour warranties on this official, non-grey market gear. Otherwise, the gear itself is the exact same.
So if the warranty is worth the extra few hundred dollars to you, then get official gear. Otherwise, I don't see a problem with getting grey market gear from a reputable dealer, especially since there is usually at least a one-year seller's warranty on it anyway.
Incidentally, I wonder if there's ever been a case of "counterfeit" Leica gear being sold as new, genuine equipment through grey market channels? 😕 With the amount that new Leica gear goes for (even in the grey market), I figure it might be worthwhile for some counterfeiter to either repurpose existing lenses or even build their own low-cost "reproductions" of Leica lenses and sell it to unsuspecting buyers...
