I had a CS3000, I cant complain about the saw. it was nice, though not the most powerful I could get, but it was light, and easy to handle for my needs at the time.
The biggest problem I had was the intenz bar on the saw, it kept sliding back and driving me #@$@$!#$ nuts. I eventually got tired of it and stuck a screw tensioner on it like many others have before me. Other than that, I have no real complaints about it. worked well, ran when I needed it, and cut pretty well for a 30.1CC engine, I liked it. next time I'll buy a CS340.
