No offence Frank, but how can the price of these devices be justified?

This is around 1600 pounds sterling (I am in the UK)

WOW

Don't feel picked on BTW, all the commercially available units that I can
find online seem to be overpriced by a factors of 2x or 3x

This is precisely why I want to go down the DIY route (with some help
from normally sighted friends).

Exactly right. Suitable cameras, monitors and computers are dirt cheap --
if you're lucky you can retrieve them from somebody else's garbage! The
problem is the indexing table. Something appropriate might be constructed
from a drafting table and the thingy that clamps onto it that allows you
to draw parallel lines etc.

My MIL wrote her grocery lists in 2" letters, but if your vision isn't
that bad you might not need to move the reading material around much at
all, obviating the problem.



I just tried writing 11 figure phone numbers down and re-reading them fast
enough to dial without serious pausing.
I needed 30 mm minimum height, so while not _quite_ as bad as 2 inches (51
mm) .....!
It is easier to keep phone numbers on the computer of course, one can scroll
a cell of Excel (containing the number) to fill the width of the screen,
which is a 26 inch LCD tv in my case <g>!

Yes, the indexing table _is_ a problem, from a design point of view, but not
the be all and end all.
