Yep RED7 was the film I was looking at.

And the 1000$ AUD is a bit of a steep
price of entry.  But I Think it might
be worth it even if you can't find a
friendly person to give it to you 10
sheets at a time.

It's just comical that the cost of
consumables will exceed the cost of
hardware 10:1

the garage just waiting.

My only concern is if sticktion is

Time will tell.
