If customer service is important to you then you have to stop in and see the friendly staff at Vegas Vapor Emporium. I just bought my first vapor a month or so ago and haven't smoke a cig since.
They are so knowledgeable and helpful and will spend hours with you without the pressure of salesman. They also have their own lab and make their own e juice, which is important to me because I know exactly what I'm smoking. If you want a healthier life and are considering to quit the bad habit, then I highly recommend VVE. Oh yea, and they have several tables and offer free coffee and RockStar. They encourage the Vapor Community to hang out with free WIFI, etc. Great people
