Tom, Contact any blueprint company or office supply company in your
area and they will be happy to give you lots of information.  Also,
your institution's purchasing officer is usually willing and able
to help with source information and your library's business reference
section will list many sources.  Most have 1-800 tel numbers and publish
catalogs which they will send by return mail.  Prices may surprise you
on this equipment; many institutions require that such purchases go out
to bid and so the process can take a while.  Good luck!
