I've played it (real hardware, converted Tempest cab, spinner) quite a bit. It is a unique and excellent game. I really enjoy it and think it belongs up there with Tempest when the production run is considered. $5000, definitely not, but that is only for a perfect dedicated. They only made like 500 of those. You can get a conversion kit for Tempest much much cheaper.
It is definitely one of the best vector games.
