I've got a BS350. I bought it for small work as I have a large cast machine for my main ripping so can't comment on it's ripping ability.
I use it for shaped work, hardwoods mostly up to 60-70mm thick, with 6 -12mm blades from Axminster. (I know, but I bought a load before I found this site and realised there are good quality blades out there)
I'm not overly impressed, but it does the job. When I looked around the various other options in the price bracket it seemed to be the best available to me at the time.
The guides work well and are reasonably easy to set, the bed is solid and doesn't move in use. The wheels are more solid than most, some were quite a light alloy. By biggest things with it are the fence not coming on and off with out having to get out the allen keys and the tensioner seeming a little weak, although they all seem that way in this price range.
