John,
I used to teach at a small college in the upper midwest that had a 35mm only program. I decided to add large format to the curriculum. Since I was primarily teaching younger students, their eyesight was good enough for 4x5. But the school's art budget was a joke at best. So, I purchased the equipment myself, and like you, wasn't independently wealthy.
So, I bought 3 old Calumet view cameras (and a Kodak Masterview for parts). I happened to have 3 210 Symmars. For tripods, I went to a pawnshop and picked up three surveyor's sticks. (They were happy to get rid of them so I got them all for around $30) Made adapter to take a tripod head and bought used Bogen 2047 heads-not my favorite, but adequate. For meters, I bought 3 used Gossen pilot meters.
Once it got around that we were doing large format, people "found" old cameras in their basements and barns (literally!) and wanted to know if we would like them. Through their generosity, we added a couple of 4x5 and 5x7 Grovers, and 2 8x10 2D's. We also receved some full plate cameras that we ended up selling to buy other equipment.
Incidently, film holders and even a polaroid back came with the cameras.
It's great that you are thinking of this project, but are your students going to be able to carry all the equipment? Good luck.
John
