Monday Munchies- Hydroponic gardens?

We have a very tiny yard, and I love vegetables. Winter is always hard for me because vegetables are so expensive, and tastless during those months. So, I have started looking into making a hydroponic garden. This way, I can have all the homegrown tomatoes,herbs, and spinach I want year round. I've seen some great explanations on the internet. It looks like you can use a rubbermaid container for holding the plants. I even saw one where the guy had a drip system set up on a timer. That is kind of what I'm wanting to do. My only issue, is that I don't want to waste money making something that may not work out. While I do have rubbermaid containers on hand, the lights and nutrients aren't cheap. Brian has teased me that I don't have a green thumb, (I have a black thumb.) I tend to kill plants. It's sad, but true.

Have any of you ever made a hydroponic garden. (Even if only for a science project?) Do you know anyone who has made one? I'm really hoping to figure this one out. I'd like to start one soon. I welcome any suggestions you or your friends may have. I'd love to know what works and what doesn't before I spend the money. This is what I'm picturing (minus the kitty.)
