1) Leica M2 or M3 and lens such as Jupiter 8 or Industar 61
2) Bessa and early Leitz lens (summitar etc)
The setup will be my daily shooter, so which of the two varieties of lenses would be more usable? I've seen some Summars for around $220, however these seem pretty unusable due to the lack of coating etc. The cheapest Summitar on evilbay is $325. Would this be more usable than a Russian lens?
First I would think about the focal length that you are most comfortable with. You seem to want a 50mm. For daily use most people seem to prefer a 35mm lens. Personally I like 28mm very much. As for the lens options you have listed, I have very good experiences with the J8 (if you manage to get a good one). The Summitar is also very good, but mine stops at f12, so the J8 would give you more versatility, but I like the image quality of the Summitar slightly better (if you manage to get a good one). Mine is coated and some users seem to report a proneness to flare. I do not have that problem.
As for the body, the Bassas are perfectly fine, the screw mount Bessa R pairs quite nicely with the Summitar, but you won't be able to use M mount lenses. The finder is quite nice and the built in light meter is convenient. The M2 is quite nice also, if you like a classy, classic look and the built quality is exceptional. Loading film is a bit fiddly though and you get 35/50/90 framelines. The M4-P gives you more options with regard to framelines and film loading is much easier. It does not project that much class as the M2 though, if you are after that. It's more like a hands on tool.
These M's come without light meter, so you have to be comfortable with using an external one or none. With experience you may tend to use the meter less and less anyhow, as you learn to judge lightning situations by using an external meter. Takes some time though.
So from my experience in your situation I would put the M4-P up high on the list. Think about your preferred focal length. Once you are sure about your focal length I would not make too many compromises with regard to the lens. If your desired lens is out of reach, wait and don't buy yet. In the end you will save some bucks. Test before you buy. However, in the realm of 50s, in my opinion, the J8 is a valuable choice, given you mange to get a good one, and they are not very expensive.
Another route to RF photography would be to just buy a compact RF camera, such as the Olympus 35 RC/RD, XA, Canonet QL , Yashica Electro and so on. You may just want to buy one and see what you can produce with it, save up and base your future gear selections based on your experiences made with this one camera. Just my 2 cents, good luck.
