    No, I'm not contemplating teaching spherical geometry to students, but I'd like to get one of these for my own edification. I've seen just one supplier in the UK offering these at a shade off £100 (are people really taken in by the £99 nonsense). This seems somewhat excessive for what is essentially an 8" polycarbonate sphere, with a few accessories thrown in.
    So does anyone know where I could buy one at considerably lower cost? Alternatively does anyone know where one can buy decent sized rigid, clear, plastic spheres: then I'll make the accessories that I want.
