If you can do without the light meter the M2 should be great. The Leica lenses are so incredible easy to focus that they beat the autofocus. The only tough part is loading film. See Tom A's video on the subject. His trick is to fold the leader before inserting it into the take up reel. The fold hooks onto the reel.
On my M2, I have the Leica easy load spool. It is amazingly easy to load, just like it says. Don't have to fold it. Can do no wrong.
It is not about the quality, really. It is sometimes about the sharpness of the optics, but that's less important than what it is REALLY about. It is REALLY about how it becomes a part of the body. I shot for editorial with my M2 and M4 for over a decade, and working was just an easy flow, it was like a dance.
I still have a beater M2 and (horror of horrors!) an M5. This is the only mention of that pariah of the Leica line so far, I believe!
Actually, I absolutely love that M5. If I get some money sometime, I'll buy another one. It is probably the best of them all, but for some reason, it has been regarded with everything from disdain to outright hatred. Seriously under-rated. So many great things about that thing. What a great meter! But it is shaped differently. If you got mugged, though, you could put a serious dent in the mugger, and the camera wouldn't notice. And they don't cost quite as much.
Here's what I think. If you aren't going to USE it, forget it. Don't buy a pretty one. Buy an UGLY one that works perfectly. Buy the worst one you can find and send it to Sherry or DAG for CLA (how's that for acronymy? Almost like the CIA!). Consider that a part of the price. Sherry will charge about $250 or so.
My M5 looks great, needs shutter work, and I'll send it in as soon as a ship comes in (or at least a small boat). The M2 works perfectly, has lost half of its covering and has someone's driver's license number scratched into the back of the top (not my driver's license number). I got the body for $400. I have the CV 40mm Nokton f/1.4 in the single coat version; love it.
