Most companies can't afford to make dubs for anime nowadays. DVD and Bluray sales aren't strong enough to warrant them in most cases, and few series air on English-speaking channels nowadays. Unless it's a big name title that's guaranteed decent sales, it's not gonna get dubbed. Also, many of the series on HuluPlus probably have dubs on their home releases (Pretty sure a lot of that stuff is from Funimation, the last US anime company that regularly makes dubs). If you absolutely can't stand hearing a language other than English and are too lazy to read a couple of subtitles, pony up the money. Or steal it. People who actually pay attention to anime with any seriousness don't give a damn about that old sub vs dub debate, since most of us watch stuff as it's released in Japan. Dubs are obsolete.
