just because they are rare and make a bunch of noises . seen them go for hundreds of dollars . they are pretty cool .had a few in my day .
they have a nice bucket brigade echo,built in variable talkback with speaker ,a speech compressor,unkey tones ,melodies that you can play in the background and talk over ,a scrambler feature that scrambles your audio so only another vc100 can decode it .
they made a vc100, a vc200, and last but not least a vc300. if a bidding war starts they can go for hundreds .
pee refers to the unkey tones that are selectable on the rear of the unit with dip switches
