Actually, when I'm writing dialogue, I use movements INSTEAD of dialogue tags (he said/whispered/explained). In fact, I try never to use dialogue tags unless there are more than two people in the conversation. Once the people have been introduced, it's no longer necessary.  Here's an example from my latest (it's paranormal by the way--shapeshifters):

Yes, yes, yes, and once again... YES!

I have three rules when writing dialogue:

1. No adverbs: "...he said stiltingly."
2. Use "he said/she said" as much as possible in dialogue attribution
3. Try to use descriptive text surrounding the sentence in place of dialogue attribution as much as possible to bring the scene alive.

That last one, once you get used to the technique, is the most fun way to write dialogue.
