Yeah, I’m really interested to try that out, but agree that it is expensive. Plus, as far as I can tell, it doesn’t have the ability to advance each frame, so would be pretty slow to use.
You should also check out the MK1 from Negative Supply.
I have a beta unit on loan from them, and it is awesome. You use the knob to advance and align each frame. Here it is in my setup.
Super fast, super flat. Got through an entire roll of 35mm film in about 3 minutes, and the results were great.
