El C., I did the same thing! I still have loose Bespin Luke, Bespin Guard, and Squid Head heads, and my oldest Hoth Han's head is glued on. (Not that he has a younger and an older head, but that, oh nevermind!). The Biker Scout was the most popular one, since Stormtroopers didn't have removable heads, but somehow he survived the gulliotine (sp?).
