I forget where I saw this, but it's been a great success for me. You know those old-style milkshake machines? The ones with the metal cup that fits under a stalk that spins the contents into a froth?

Try putting your eggs, seasonings, cream and a tiny amount of oil into that cup, and whirl for about three minutes.

The omelette turns out so thick and fluffy I sometimes can't fold it at all!
