I don't know what site you are looking at. On mine, on each of the catalog pages the price is clearly stated near the bottom as $3600. See http://www.tobincinemasystems.com/page47.html
The H version does transfer frame by frame, actually field by field. At the NTSC 17.126 FPS speed there is a 3:4 pulldown, meaning that one film frame goes to 3 video fields and the next film frame goes to 4 video fields. PAL is simpler, at normal speed it is just a 3:3 (or would that be 3?)
This field by field transfer, I believe, gives smoother screen action and less motion "judder" than transferring frame by frame, and then copying whole film frames to alternating 3 and 4 video frames.
At half speed the pulldown on NTSC is 7:7 (7?), and at 1-1/2 times speed the pulldown is 2:2:3.
This is with some tricky shuttering where the virtual shutter changes from 7 to 3-1/2 to 2-1/3 blades depending on the speed, synchronized to the video and to the film pulldown cycle. Try doing that with a physical shutter.
