For perspective: In1979 I bought a used Arriflex BL that didn't have Arri inspection, maintenance, certification and warranty. (I knew and trusted the source.) According to the Bank of Canada's inflation calculator, the dollar then was worth 2.4x what it is now. So the $6,000 I spent then would be $14,400 today. Mind you, my purchase then included the workhorse Angenieux 12 - 120 zoom. Just sayin'.
