While they were not my primary 80's joy (that goes to GIJOE), I was and am a big fan of the transformers.
The first one I ever owned was Wheeljack. I bought him for $3 from a classmate in the 5th grade. Later on that year, I got Skywarp for my birthday.
Later on, a buddy of mine traded me all five Dinobots for some of my dad's old Playboys (internet porn hadn't been invented yet). Later on, I realized that they were actually his little brother's toys!
But I still kept them.
While I never had a big collection of the original Gen 1's, I played like crazy with the ones I had (regularly beating up on the couple Go-Bots some well-meaning but obviously non-toy savvy relative bought me when I clearly said TRANSFORMERS
I was always a bad guy fan so I mostly had Decepticons (and Cobras). I loved any of the Beastbots (Insecticons, Terrorcons) and the combiners.
I just can't believe they are 30 years old. Sheesh.
