My first major post-toddler toy was a model of the enterprise that just went around and around in circles attached to a pivot. It even had a "remote" control that just made it go up and down and backwards
Fascinated by the communicator and the old skool phaser gun, and I didn't know what Spock was looking at when he looked in that contraption on the main deck of the enterprise but I wanted one
Oh and Uhura was damn sexy though I didn't realise it until I was a little ollder that there was a lot of skin on Star Trek The Next Generation was tame in comparison LOL
