They're not meant for the average Joe!
They are meant for high angle rope rescue teams, namely USAR and FD rescue teams.
Those prices are actually about what I would have expected them to be. IIRC, even just structural firefighting videos cost over $200 for just 20-30 minutes worth of video.
Seeing what those videos were for reminds me of a report written in Fire Engineering mazagine sometime in the last year. IIRC, in Nebraska somewhere (around Lincoln?) a crew was working on installing new cable in a 1000'++ tower. They were using a winch mounted on a truck on the ground, something broke, and and it came whipping past a guy at 900'++ elevation. By the time a plan was formulated to get the guy down, he was dead (they weren't sure if he died immediately or later though)
. Took something like 10-12 hours from the time of the initial call to the time they got him down....
Can you see now why they cost so much? NFPA stuff is a lot stricter than ANSI Z133, that has something to do with it too.
