I love Buck Rogers, I watched it faithfully as a kid every week and as an adult I've worn out my boxed set. It's the perfect 70s entertainment for me, cheese, sci fi and sexy all sloppily tucked into an ill fitting spandex jumpsuit.
As a kid however, the closest I ever got to the toys were when my pal Jason visited and I got to borrow his figures for the day. For some reason, my mom truly drew the line with Buck toys, it was a complete no go, which was weird considering I watched "Battlestar Galactica" maybe five times as kid and had the whole first wave. I'll never get parents, maybe she just didn't like Gil Gerard.
Check out the Mego Museum's Buck Rogers Gallery.
Also, A scrappy company called ZICA toys is set to release Mego like 8" versions of Buck Rogers, Tigerman and Hawk this summer and they've even promised a Twiki in wave 2! Check out the awesomeness of the headsculpts here.
