I Need Help Choosing A Hydroponics System, how to choose a hydroponic system

I am thinking about trying out hydroponics. I dont really want to right now, as I am really getting good at the organic soil gardening, and im not trying to fix something that is not broken, but for future reference, the near future (by winter time), I would like to know your personal hydro experiences and the pros and cons of soil vs hydro. I know the basic stuff, Im interested in personal experience. A pre-built grow box like the ones from http://www.homegrown-hydroponics.com look the best to me. The green thumb runs in my blood so i know i could get it down eventually, and I expect some trial and error in the beginning, but i would love to get to the point where i can choose between soil and hydro. Any suggestions would be appreciated.
