1942 = nectar of the gods...for $100 at spec's. right now, i'm working on a bottle of gran centenario anejo and don julio reposado. i've not tried seleccion suprema, but it's regarded as one of the finest spirits in the world. i've always been curious about cazadores. the espolon tequilas are excellent as well.
I usually stick with Tres Generaciones either Plata or Anejo because you can get it for $29.99 a bottle at Trader Joe's in LA.
That being said, I have a difficult time with Tequila neat. I prefer a little ice and a little lime if I'm going to sip it. And it has to be 100% Agave. (Actually if it's NOT, then it's not really Tequila in my book.)
