I have lots of Kenner figures, vehicles and playsets. Most of them I had as a kid, but I picked some up in the r.a.s.s.c. newsgroup back in the day. It was ebay before ebay! And I have an eye out at rummage sales and the lot.
I used to think I was saving them for my kids. I have kids... they're not getting anywhere close to my toys!
It's mostly in boxes in my basement. I have a few vintage Transformers, Mask, Voltron, toys down there as well... but it's mostly Star Wars.
