This is definitely NOT true. There are as many cheap knock-offs as there 
are cheap factories and cheap vendors. There are tolerances on diameters 
of the center pin and center receptacle, there are poor/cheap choices of 
metals, dielectric that melts when you solder to it, metals that don't 
take solder, even dissimilar metal issues when mated with another 
connector. I've also seen threads that are too short, and outer rings 
that are too short. And that's just PL259s.

What IS entirely right about Bob's post is the importance of making 
connectors wrench-tight.
