Skydiver was the best piece of tech there. I *so* wanted a Skydiver toy but never could find one. Did have an Interceptor, and a Mobile. No UFO though. And no Skydiver, boo. Maybe one day I should model myself one in 3D... actually I wonder if someone has already, usually a fan has already been there and done that... yup! There we go:

Not 3D models, but just some shots of the models used in the series, useful if you wanted to model any of them:
