Helpful Tips on Hydroponic Herb Gardens?

I have been wanting a Hydroponic Herb Garden for the Kitchen like seen on T.V. but it is expensive. I have tried herb gardening from seeds and plants outdoors in Florida but they usually die out before I can get them to grow. The only thing I have now are two beautiful Rosemary bushes. Do you have any tips or ideas on what I can do to put together a decent looking herb garden in the kitchen area.I need tips and advise please.
