Whats the difference? I know that PDI is the "premier" retailer for the VSR-10 (according to ASGI). Laylax looks less expensive...and finnaly, Polar Star only makes Bar-10/VSR-10, and (as I've heard) is relativly new. I've heard good things about them though...
P.S. If the question has been answered ON THIS FORUM, provide a link please. I could not find any topic on this.
