The Firestorm looks very nice on paper, and i think you'd be happy with it. The link i provided is a combo deal - so you'd be getting everyhting you require to get it up and running (you may need a glow-plug). You're saving a fair bit of money with this deal, and shipping should be free.
...just something to think about
