You do not need the film holder for scanning negatives or
transparencies on the Epson 2450.
The holder is used for getting thumbnails on the scanning software so
you can do some some things
before the image is scanned.
You can just place the negative under the light and the scan will take
place as a flatbed except you have
scanned a negative.
This can give a great deal more versatility and I have also found that
the thumbsnails software often
malfunctions.

I use Polaroid Type 55 with lenses and pinholes. Depending on where
you get your BW processed (I don't have a darkroom) Type 55 can be
cheaper than normal films plus development and contact.
The print and the negative are not the same speed, so you can't get
both from one exposure. Normally I want the negative, and I use a
speed of ISO/ASA 25. I haven't done any serious reciprosity testing,
but for long exposures I add a stop (after correcting for the pinhole
exposure). Polaroid has datasheets up on their web page.
When I got my Epson 2450 scanner I discovered that Type 55 negatives
won't fit in the film holder. They're a little bit wider than other
4x5 sheet films.
