From what I have read on another forum (of which will remain nameless here) Aztec is mainly a broker. While this is not a strike against them (folks think that dealing with brokers is a bad thing but that is sooooo not true) I have found that they are not the best broker to deal with as they seem to not have the skills to qualify thier sources brfore collecting money for orders for their stuff. In other words, they are lazy brokers that do not take the time to find out if the suppliers they use are in fact legit and trustworthy.
While I have heard they are nice people and easy to deal wth, the fact that they have brokered deals for crooked dealers in the past and claim they did not know the dealer was crooked raises a BIG red flag with me. they may be honest, but they are not good brokers to deal with (only what I heard. i have never dealt with them personally).
