1. Any anime shown on TV will be the US edited version. Trust me, they absolutely SUCK compared to the Japanese versions!
DVDs are normally uncut and in english. I'd rather not spend the bulk of my viewing time keeping an eye on the bottom of the screen,

2. No series will be released on TV before it's available on DVD. So you'll be waiting a long while to see stuff like Last Exile, Stellvia, Full Metal Panic? (Fumoffu) and so on. Trust me, find someone who downloads fansubs and get it from them. Fansubs >>> dubs IMO.
Downloads are free too, but DVDs are a decent substitute if needed.

But Dubs > Subs of any kind. I can fully take in the animation and they don't strive to be as accurate, letting in little english idioms and pop culture. That and if there's any chance of Richard Cox being it in, it's worth it.
