30 l/s is an awfully small pump for those big bucks. As it is a nice Varian unit with magnets and if it is clean and not all clogged with crud. The price is not outrageous, just stiff.
The controller is un-necessary if you have any HV power supply construction skills. The beauty of having a proper controller is that most include a vacuum gauge readout based on the action of the pump in use.
The bottom line,..... if I had to have a nice ion pump right now, had $300 to spare, and was assured of its cleanliness, I would probably go for it.
