Our First Wedding Casualty

Our beloved Lil' has mysteriously been wounded. We found her on the floor when we got home last night, still doing her job. She has been a bit more... mobile... lately. She will move closer to the edges of things and has fallen a couple times. She has also been louder, so we decided to take a closer look and see if something had worked itself loose. Part of her back casing had separated, but thats easy. We took her cover off and noticed that one of her blades had a long crack in it. That would explain why she was louder and off balance. We are going to super glue her back together, with any luck. Any suggestions on a glue that works on plastics?
