I just picked one up the other day. I really like it. It's a nice little size and weight for carying around, and of course it can often be an advantage to have a auto meter. I have only just started using it and have not developed nay photos yet, but I will post some as soon as I do.
I bought a new CV 40mm 1.4 lens for it (and to share with my R3A which is also a 40mm). So I am kind of glad it doesn't take a 35mm - I can use the 35mm on my Leica's but this CLE has given me a good excuse to buy a fast, well reviewed, 40mm lens I doubt I would otherwsie buy. I was thinking of using the CLE with the 40mm 1.4 for night/indoor photography - taking it out a=nd about when going out at night.
I pikcek it up from MW classics in London, in good condition and all working, for £225, which is less than a second hand R2A or R3A usually goes for, so I think you can get one for a good price.
My only problem is, as I have becom a little obsessed with getting rangefinders, I also picked up a Konica Hexar rangefinder the other day - which reviews suggest is a slightly better M copy, and also has AE mode. Plus it has a top speed of 1/4000 which i believe is faster than the M7. I got that for £355, so a bit more than the CLE or Bessas, but still much less than an M7.
So now I have too many "second cameras" I don't know which one to use. However, I have them all for less than the price of an M7, and I can use my M6 whenever I don't want AE, and my M4-P if I don't want metereing issues at all. In fact with these used cameras available out there, I can't see the justification for splashing out on an M7 - but no doubt someone will shoot me down for suggesting such heresy
