Most of the ones I know of are 7 strips of 5.  Paterson used to make
a 6 strips x 6 exposures and I think they had a 120 - try ebay.

I just looked, they still make it -- but as you said $75 - Yikes!
I know they go on ebay in the $15 range.

I have a 7x5 Saunders that's sort of a pain but works well and without
glass.  I often just put the negative filing sheet in a contact frame,
which is what I do with 120.

I used to lay the strips on the paper by hand and lower a sheet of
glass over them.

** Cheapest solution -

Buy some double pane glass 10x12 (allows one inch on each side) from your
friendly neighborhood glass shop.  Double pane because of added weight
Store negatives in clear plastic holders.
Place glass over negatives in holders over enlarging paper.

** More pricey solution -

- Patterson Pro Proofer

- Porters Camera 35mm contact proofer

** Recommended solution (by me):

- Saunders Super Proofer -35 and -120  (no glass!)

These work like a charm!  I've had mine for over 15 years and they still
work today as well as they did when new.

Using the PrintFile negative sleeves and a double thick glass pane
larger than an 8x10 paper should cost no more than ten to fifteen
dollars at the most. It works easier than a proofer. You need to put
the negatives into a proofer then afterward take them out and place
them into the negative sleeves. Using the clear negative sleeves and
the glass to hold them to the paper is so much easier IMHO. And
faster.
 The PrintFile 35-7B for 35mm film(Holds seven strips of five
negatives) and the 120-4B(Holds 4 strips of three negatives) fit an
8x10 paper and fit in a standard three ring note book without sticking
out of the cover. So you don't damage the end negatives.
 I am sorry to say that a lot of sales people today have no concept
of Proofing negatives or making contact sheets. To much digital.

Getting even isn't good enough.

Doing better does.

Paterson makes three proofers, 35mm and 120mm format
specific and an oversize 9x12 that's all I ever use.

The Paterson 35mm shows up used once in a while but the
"mask" that holds the negs is a bit of a pain and the frame
numbers have to overlap to get it all on one sheet of paper.

I used 8 1/2 X 11 paper for years now I just shoot 30 shots
per roll, bulk loaded and proof 5 strips of 6 per 8x10 paper.

BTW I don't like the Patterson 120 since it does 4 strips of
3 (OK for 6x6 but does not work for 645).  I prefer 3 strips
of 4 and buy printfile pages since they also work for 3
strips of 5 for 645 (if I had a Hasselblad 16 back I'd buy
the other pages also).
