This whole movie was wonderfully disconcerting, on many levels. Made me think also of "Inception's" premise of "a dream within a dream--within another dream!" Wake up or find yourself in "limbo" for the rest of your life!
It may be a moot point as it appears--from CineMartin's website--that the remaining monitors were sold as a package to "a big customer." And if--as David Yao points out--their customer service is poor, they won't last long. I have a Lilliput monitor and I'm told the Neewer's are good, as well, so there are other modestly priced offerings out there. BTW, the $299 was actually EUROS, so the price is actually higher, in US dollars.
I downloaded this "crib sheet" from another location, but I LOVE IT!! Only wish they had created one for Audition...bummer!
