Favorite Aromatherapy Essential Oils Brand Recomendations?

I'm looking around to buy some good quality essential oils to use with my new UD vaporizer. What are your favorite essential oils and/or brands to use?

Doterra. .. they really are that much better.

I am just starting to experiment with this. I am using some free Doterra stuff right now. Its nice but expensive. In my research I found Aromatics International. They come highly recommended and if I ever wish to purchase this kind of thing this is where I will do it.
