Mick,
I've got an LPL 7700 just sitting in my garage. My missus wants me to do a cleanout, so if your student wants to have it, they can contact me on mwynd@gordontafe.edu.au. $50.00. It hasn't been used since my dad died, but it's in very good nick and comes with 50mm, 75mm and a 90mm.
Cheers
Mike Wynd
