I stopped by the EFX booth at Comic-con and they had some Doctor who props they were getting ready to produce. The difference is, the guy who works with this company (who I talked with for about ten minutes) actually build the original props for the show, including the sonic screwdriver, laser screwdriver, Cyberman helmet and a full size Davros bust. Their Sonic screw driver, which is amazing, costs about $200 and will be available in November.
