Most of the guys in this film are probably members of this forum.
I am a very low level collector and I've managed to accumulate 5 cabs in 3 years, 2 of them working when I got them.
One thing I hope this film expands on is that this is not necessarily as expensive as it sounds. The general public has this notion of "OMG, how much did you pay for that?" but in reality cab collecting can be pretty cheap.
Let's say you spend $500 per cab. Most Americans can handle putting $100 of their paycheck away every month. Save up 5 months and you have a cab. Do it twice a year for five years and all of a sudden you have a home arcade of 10 cabs.
