Yeah, I love good tequila! Don Julio is my favorite these days as well, the Anjeo and Repasado are typically in my cabinet. When I want to treat myself, I pick up a bottle of Don Julio 1942. Few bucks more, but very very smooth. They also make a "Real" I believe, thats stupid expensive and I have not yet tried it. One of these days!

Get out there and try stuff, and you will find there are good things about many different types. Sometimes BevMo and Total Wine near me will do a tequila tasting or get vendors in to do tastings. Those have proved to be enlightening as well.
