Thanks for the feedback.
To be honest, I'm not much of a tequila connoisseur. I just like to take advantage of the duty free allowance to build up a nice selection of drinks for parties or get togethers. My friends will not drink tequila unless it's "good" tequila.

Will definitely look for 100% blue agave. We're doing a Mexican Riviera cruise so we'll probably hit the Walmart in Mazatlan or Puerto Vallarta. Thanks for the brand and specific product suggestions.
