Favorite GF Beers?

I was diagnosed with celiac disease about 3 months ago. Since then, I've made it my quest to find a good GF beer. I have been to many lands and have yet to find good brew. What are your favorites?

Also, I hear tales that Heineken is produced with such a low amount of barley malt that it can be considered by many standards to be GF. Anyone know if there is truth to this?

Edit: Just went to a GF store in Italy and picked up 2 different brands. Estrella Damm Daura and Riedenburger Gluten frei. The Riedenburger tastes like pear-flavored gypsy urine. However, after the Riedenburger and 3 months without beer, the Estrella DD tastes great. It tastes like good beer, as far as I can tell. I highly recommend it! I don't know if it is available in the US, but I sincerely hope so.

Hooray Beer!
