Well, I got it with the Orange Box (only way to get it retail) for $50 and it is by far one of the best multiplayer games I've ever played. It's quirky gameplay takes a lot of... pissed off-ed-ness out of being killed over and over again. The teams are perfectly balanced and in order to win, you'll probably have to switch classes quite a bit. Overall, a great game... WELL worth $30.
