Hi,
I was in a similar situation like you when I bought my first RF about 1/2 year ago and have used some models in the mean time, so this is my experience so far:
I have used the following cameras: Yashica Electro 35 GS and CC, Olympus XA and XA2, Canon P, Kiev 5 and Bessa L.
What's really nice about RF cameras is that you can really try out lots of different outfits and sell the ones you don't like, usually with no or very little loss, provided you don't buy non-working junk.
Out of these, I think for a beginner the Electro 35 GS is a good start: It has the look and feel of a real range finder, with a well-performing sharp lens (45mm/1.7) and should cost you around 50-100 $ (in Europe, dont know much about market prices in the US but I suspect they are lower). The 35cc is a little more expensive, it is smaller and has a wider lens (35mm/1.8) but the vf is smaller and does not have parralax correction.
Oly XA/XA2 don't look like serious cameras, but they are truly superb. I always carry one if I don't have another camera with me, fits right into your pocket. I recommend you picking up one of these no matter what else you are going to buy, if you are lucky it shouldn't cost you much (15-25 $).
The Bessa L, Kiev 5 and Canon P are interchangeable lens RF with LTM screw mout, which gives you access to myriads of different lenses, some of them (especially the Russian ones, and also cosina voigtländer) are really a bargain. The Canon P is a very fine, heavy, sturdy and elegant camera, without extras like light meter or so. It has a very good vf, should cost you about 100$.
The Kiev 5 is really cheap but quite hard to handle: for example, if you change shutter speeds without cocking the shutter first, you damage the camera, if you let the film rewind handle snap back instead of carefully putting it back into position, you damage the camera, etc., etc. If I compare the 1984 Kiev 5 to my 1959 Canon P, the P beats the Kiev in every regard, as far as I can tell (except for market price).
The Bessa costs you about 100 $, it comes without vf but with light meter behind the lens. It is the most conveniant body out of the three, if you just want to go out and shoot and not think too much about the camera, settings, etc. I recommend this one, especially in combination with the awesome cosina voigtländer 25mm f/4, which is surprisingly cheap. I got both camera and lens for 200 EUR last week 🙂
Every one here surely has their own favourite, so try out different outfits, sell what you dont like and find your personal favourite. Good luck!
