I have found that if you buy a quality tequila, it is very easy to drink straight (and no, I'm not talking about shots, I'm talking about as a sipping dink).
There is a world of difference between Jose Cuervo and a quality 100% agave brand like 1800 (which is not really that much more expensive). I found the Jose Cuervo to be almost undrinkable straight, while the 1800 silver enjoyable and easy to drink straight.
