Comment on Airfoil

$25 is a lot of money, especially regarded the fact that it adds a functionality Apple should have provided in the first place. But then especially the latest version with the built-in video player does an excellent job. In fact, I've got fewer problems (none, exactly) with AirFoil than with Airtunes. Also, I got excellent, quick feedback with a working solution when AirFoil didn't work with my new Draft-N Airport Express base stations.
Even if it seems expensive at first, it does an excellent job and is well supported.
