living in the Southwest Tequila is my drink of choice and I feel Patron is very overrated there is a local family made brand called 3 Amigos that is excellent there is a high end grocery store called AJs and America West arena (where the Suns play) that sell it, here is a link to thier web site
http://3amigostequila.com/
they have a few videos in the process dropdown box
also Tequila.net has some ratings on the good stuff
