Here's a link to an episode I found on G4 on demand:
http://dl.dropbox.com/u/24398483/PowerBustice1.movThere's another episode but my dvd recorder lost it in finalization, something is going bad with my dvd recorder and it may be on its last legs.
I will interject an opinion, disregard if you don't care.
Sarah Underwood is pretty hot in a cute kind of way, but there's no comparison between her and Carrie Keagan as Powergirl. Sarah gets most of the screen time in the episodes, but Carrie Keagan makes Sarah Underwear look like an under@ge tomboy when you see them side by side. Carrie is beautiful and voluptuous, as all real super girl types should be. Yummy. Most of the time I can hardly stand to watch G4, except when someone like Carrie is on.
