Query: I have tried them all

hello there. i just want to say that i have tried just about every piece of software of this kind. i do alot of direct mail for my business and have found that this product far out performs the others. it is very easy to use. the data is very good. and i especially like the fact that i can buy more data through the cd. these guys really built a user friendly, affordable product.
