Black Lagoon & Cowboy Bebop have already been recommended, which are usually my go-to standbys.
The only other one I could recommend would be Spice & Wolf, which in my opinion is criminally overlooked.
S&W starts out a bit slow, and is more contemplative than action-y, but when the action does ramp up, it's quite intense.
It also was graced with one of the finest English dubs ever put to anime, along with a fitting soundtrack, and very nice artwork.
I'd highly recommend giving it a full viewing.
The first episode can be found here, for your convenience.
Some other honorable mentions would be the movie Steamboy {which has Patrick Stewart in it), along with the Last Exile series, though I'd avoid the English dub on that one.
Trailers for both, if intrigued:
