Are there any Supergirl comic books that aren't terrible?

I'm asking for a friend. She's very excited about the upcoming Supergirl show, which looks tonally different than any of the 539 other live-action superhero and based-on-a-comic book shows currently on air. I liked the six minutes I saw, and was a little amazed that the preview for a Supergirl television show looked like a much better Superman movie than Man of Steel, Superman Returns and those last two Christopher Reeve movies.

I started thinking if there were others similarly enthusiastic about the show, and where they would go to find some Supergirl comics, and I'm coming up blank. Post-Crisis Supergirl is just so hard to explain, you know? The more I think about it, I can think of occasional issues of a series here or there, but I can't think of, like, a good trade paperback or collection to suggest to anyone.

The best I could come up with was Supergirl and The Legion of Super-Heroes, which I've never read myself, but it's Mark Waid writing it, so I imagine it's okay.

Any suggestions? Even if only single issues from various series...maybe we can assmemble a Greatest Supergirl Stories Ever Told collection. In our minds!
