Not all American dubs have been awful.
Actually, some of the older dubs are better. Most of Sailor Moon wasn't terrible. Gundam Wing had some awesome ones, I don't think there was a voice in there I didn't like. And let's not forget Cowboy Bebop, the VA's from there were just awesome. :">
Actually, I'm kind of hoping that whoever voiced Faye from Cowboy Bebop would do Matsumoto. Both are deep, but still sensual enough. *_*
