I have a black and white darkroom. I use 4x5, 6x12, 35mm negatives and
have two enlargers.
I would like to scan the negatives and invert the image for a contact
sheet proof before printing the negatives.

On the Day Job I do exactly that with an Epson 1640XL with the transparency
option. You can gang-scan up to eight 4x5 transparencies/negatives at a
time. Doing so many at once means that you make the same compromises you
might with ordinary contact printing of so many at once, but it works for
proofing quite well. If you choose this approach, and want to use the whole
scanning bed, then you will have to buy two sets of negative holders. No big
deal, really.
