I bought a load of the Robots from these guys when I started out, decent enough cams for the money though a bit unstable in the larger sizes. I still have a couple of the large Pulsars bought on a whim but never really used.
They also sell a load of CAMP / Cassin etc gear which is a bit different from the usual WC/DMM/BD kit and worth a look.
