Hey Chris!
It's good to see you again - no, really! 🙂
Don't dump yer Nikons yet dude (and at 500K exposures, they're ready to drop anyway.) Rangefinders don't shoot everything, just like there are better tools than a dslr for some stuff. And listen to these guys when they tell you to start out slowly. There are aspects to RF shooting that are not obvious, and must be learned by experience. And if you don't click with it (and don't knee jerk say you will, cause you just don't know until you do it) then you will be stuck with some expensive junk.
I was told by the quintessential Leica fanatic that 90 percent of all good 35mm photos are made with a 50mm, so maybe that's the place to start. But the f/1 is huge, and only gets as close as one meter. Another thing, such a big lens will block more of your viewfinder than a smaller lens would.
Speaking of viewfinder, that's another area you should look at. If you are gonna shoot wide, say 35 or 28mm, you will want a wide VF, or as they call it in Leicaland, 0.78. Anything wider (like the CV 12mm) and you'll need an external VF. If you are shooting a 50mm, you might appreciate 0.85 more. That will lead to more accurate focusing, and more comfortable framing.
If I had your money, I'd get an MP through the ala Carte service - black, no engraving, and the angled rewind knob. You can always $ell it for about what you'll pay if it doesn't work out between you two.
eta: just saw you are getting a 35mm lens. Cool, that's what I have.
