Hmm, There are a lot of good animations out there, and unfortunately even more poor ones. I think you might enjoy Cowboy Bebop, NTHT (Now and Then, Here and There), Record of Lodoss War, Rorouni Kenshin, Outlaw Star, Trigun, and Escaflowne, for starters. Also, it's worth noting that I watch all anime in the original Japanese dialog with English subtitles, as I vastly prefer the Japanese voice acting. So as a result, I cannot vouch for how good the spoken dialog would be in the US/English overdub versions of any of the anime I've recommended. I'm sure Big B will have dozens of suggestions for you as well. :)
