I just watched a 9 part video on youtube where the guy grows with hydroponics. I have to tell you, even though the video wasn't the best quality, and it's not exactly thee best video on hyro growing ever, he still got me really wanting to do a hydro grow. It not only seems like it would be more fun, but it turns out that plants actually grow faster (and possibly somewhat better) without the soil. With soil you have problems with time released ferts, dirt clumping up, pH levels that are somewhat difficult to fine-tune, and some difficulty getting oxygen to the roots at times; but hydroponics solves all of that. Not to mention it's a whole lot cleaner and prettier.
Once I finally got over the idea that plants need soil to grow (which the oh-so-useless education system beat into my head) I actually like the idea of hydroponics a lot better.
I'd say go for the hydro (yeah, I changed my opinion). I'll link the video. Maybe it'll give you a push in one direction or the other. If nothing else, it does accurately show you how to easily make your own hydroponics grow room quite well.

Sorry for clogging up your grow journal.
Good Luck with whatever you decide!
