Lecture notes on representations of finite groups

The middle third of Serre's "Linear Representations of Finite Groups" is excellent. It's in 3 totally seperate sections, the first third is ok but very elementary and the last third is tough going. But the middle is "just right."

Some material from the undergrad rep theory course in Cambridge: Example sheets, A recent set of notes (by Martin), and a less recent (but very nice) set of notes (by Teleman).

I enjoyed Pavel Etingof's lecture notes for his representation theory class, which can be found here: http://www-math.mit.edu/~etingof/replect.pdf (there is a link to it on his website) They move fast, but without skipping too much and still providing insightful proofs of results.
