I am an architect. I recently began using the extra large (7.5" x 9.75") gridded Moleskine cahiers for my note-taking. They are nice, but, what would be even nicer would be a notebook of a similar size featuring a dot grid. Instead of defining the grid with lines, just dots at 5mm vertical and horizontal centers.

Behance offers one but it is too pricey at $14.00 and I really dislike perforated pages; they all too often come loose of their own accord.

Have you any suggestions as to where these could be procured online?
