Do you really need 40MHz for educational purposes? Unless this is a device to be used in a college or higher education class , you can display sub-10KHz signals to teach a class how to use a scope.
They might need the higher bandwidth - seeing what the kids these days are doing in every aspect of technology, blows away anything I ever came close to. A good tech teacher won't stick to old curriculum, but try to expand the class as close to the leading edge as they can.
As far as getting a scope, I too suggest the "real thing". I bought a 20 Mhz scope at a local utility auction last year, great shape, $100.
