Reflectors with an effective collecting area under 4" are worthless. That's everything from the aperture to mirror. That's going to put you well over $50. Adequate reflectors don't exist under $250, except on special clearance.
You are better off buying a remotely controllable reflector with a webcam fitted to the eyepiece and having a group of kids take turns steering it. Firstly, it's cheaper overall. Secondly, you don't have breakages to worry about. Third, kids prefer nice, warm rooms to freezing pitch-black country parks well away from light pollution, hot drinks, facilities,
Not only is this more likely to be attractive to kids, parents who invest $50 in a group effort are much more likely to make sure they get their money's worth than if they spent the same amount just on their kid. It's all about the attitude of not wanting to pay for someone else's stuff. It's a vulgar, uncouth attitude, but that makes it easily exploitable for everyone's gain.
