I saw that show and was calling BS as soon as they started talking about it's value.
If I remember correctly, and this is going back a couple of years now, that marker came with that splash anno, but it was more of a special edition upgrade of a Spyder TL? I could be wrong. Everyone else is absolutely right about it being worth maybe $100 plus the hopper. They were also touting the semi, 3 round, and full auto abilities. But all of that comes from the electronic trigger frame which is still based off of a mechanical trigging of the bolt release rather than the firing of an electronic solenoid as most modern electronic markers. So even that is limited in speed compared to any modern gun. It looked like it only had a 10 inch barrel and when they were shooting it, every shot was curving off target.
As to the "banned in competition", at the rear of the gun is the velocity adjustment and as per the 2012 PSP rule book:
pg. 22 9.3.9 A marker with settings, whether mechanical, pneumatic, or electronic, that may be adjusted without the use of tools to allow the marker to operate in an illegal manner is illegal.75 A player who operates buttons, switches, valves or other adjustable device on a marker on the field of play without the permission of a judge will be assessed a minor penalty.
A player who operates buttons, switches, valves or other adjustable device on a marker on the field of play after being instructed to provide the marker to an official, or prior to being instructed to do so, will receive a gross penalty and that player will receive a minor suspension.
So yes that particular marker had a velocity adjustment knob on the rear of the ram that can be adjusted without tools. There is supposed to be a counter turn allen/hex bolt that keeps the velocity from being increased "accidentally" while on the field. But those are so small and they commonly fell out. Hence why marker manufacturers went away from using that design.
Finally since you can't cap the firing rate in any mode, that would make it illegal as well.
Hmm, let me buy a "tournament" marker that I can't USE in any tournament series. GREAT IDEA!
As to it being banned somehow increasing it's value is like saying an aluminum bat is more valuable because it is banned from use in the MLB!
I know this from first hand experience, TV producers think everyone that watches their shows are morons as a majority and that they can get away with saying or showing inaccurate things, because it is only the very slight minority that is actually aware of the truth and is even viewing their programming.
Just a quick example: I was working on a film in the Bahamas and I was one of the camera men, but my background is Emergency Medicine. We were shooting a scene and there were just so many inaccuracies that I tried to point it out to the director whom I had established a fairly good relationship with, but the producer (his wife) fired me the next day because I was "being insubordinate and slowing down the shooting schedule over menial details that no one will ever recognize."
Needless to say the film got bad reviews and some said that they kept getting pulled out of the story when they saw something they new was wrong. It never made distribution. I got paid, they didn't. Who's laughing now?
