A little over $200 for a one-hour reel, and that was 1960s and 1970s dollars.

It was about $1300 to re-build a headwheel, which was required every 1000 
hours or so.

Then you needed air compressors, the headwheels used air bearings, and some 
machines used pneumatic controls.

Then there were the 2" cartridge machines (RCA TCR-100 and Ampex ACR-25). They 
were an absolute nightmare to keep running.

But a properly setup 2" quad machine could make pictures that were better than 
anything today, the catch being "properly set up".

I never spliced tape myself, but I've watched it being done.
