My favorite is Chinaco. I like the reposado, but they're all good. Truly a different animal from run-of-the-mill cheap tequila. To me, the reposado straight almost tastes like a cocktail, since it's got so much going on.
The New York Times did a comparative reposado tasting recently, which has some interesting comments.


You can get Herrdura Silver for under $20 Ed??!?!?!?! Holy Crap that is a damn good deal! I picked up and since finished a bottle a while back for $29.99 on sale and that was the best I have EVER seen... I'd never run out of it at that price.
