I would rather doubt that the record companies, atleast some of them, would want to sell a non notched CD at any price considering how much they are fighting for the legislation that makes use of it. I also wonder how much of a premium will be charged for DAT units that do have the special anti pirate circuits defeated? They will be available, and they should not be all that hard to build. -- Taras Pryjma uucp: taras@gpu.utcs bitnet: tpryjma@utoronto Bell: +1 (416) 536-2821 Ok then, It's settled.
