Gran Centenario Reposado. Here's what some one else said about it "For my money, this is the best tequila value on the market today. An excellent, smooth, full-of-agave-flavor bottle, and it runs under $35 at most liquor stores! Hints of vanilla, oak (of course), and cinnamon make this a very enjoyable pour. One of my favorites! I keep coming back to it again and again. Reviewed by jzsouthern" Thank you
+1 El Jimador Nice everyday 20$ a bottel drink.
+1 on El Cazadores an all around good tequila for mixed drinks, sippin, or shots.
Corralejo Reposado. "Double Gold Medal" at the 2001 World Spirits Competition. This may have been true in 2001 nowadays the quality has been a bit spotty, but if you find a "good" bottel it won't be lacking for much.
I dont think any one mentioned Chinaco. If you haven't tried this yet, you owe it to your self to do so. Very good juice.
