G3 pixels/pg: (200dpi)^2 x 8.5 in x 11 in = 3,740,000 pixels

Last I checked, that was a USD 3,000 camera. Prices may have gone
down, however. Note that there's no way anything less than the $10K
Hasselblad backs that magazines use for studio work can equal a 600dpi

Which 35mm film are you using? There are some really nifty Kodak
technical films -- Tekpan something or other (4-digit number?) is an
ASA 25 black & white film, although you'd need a few hundred dollars
of lighting equipment to use it for this application. OTOH, T-Max 125
probably delivers more than enough quality for the job. ^_^
