I have very limited experience in this area but the college I attended had a very high attrition rate in camera gear. Most kit did not survive long before being permanently "studented"!
The TLR's they used were Mamiya C330's, all of which still worked and (when used correctly!) turned out very good images. The interchangeable lenses were a very good feature too.
They are quite heavy and cumbersome... ...but can also be used to drive nails!
Whatever you get, please show us the results in your esteemed publication. We don't get to see nearly enough of your own shots, and I've very much enjoyed what I have seen. Also many thanks for all your efforts with that mag, please keep up the good work!
All the best,
