Self watering containers?

Self watering containers?

I am intrigued by the idea of using a self-watering container for tomatoes. Anyone have any thoughts on the EarthBox or the Gardener's Supply Tomato Success Kit? Or others? I've also seen instructions for how to make your own, but I don't know that I really want to spend the time on that. The local nursery sells the EarthBox without the extra stuff (soil, fertilizer, etc) for $50, but if I go this route I kind of feel like I'd get more for my money with the Gardener's Supply kit.
