Right, I've dicided, after much thinking and asking lots of questions. I have decided that I will buy a Panasonic GS400. BUT whats this I hear there being a design fault, resulting is the mech being miss aligned resulting in a grinding noise? I have read that Panasonic are aware and wil fix the fault for free. I am right in thinking that the "newer" models from the factory should not have this fault? If so, how can I tell if my model will be free free from this fault, can i go by batch number? Cheers all.
