Townsville is my favorite name, for any city.
Hey guys, what should we name this place?
Let's keep it simple. Let's call it Town. Cuz it's a pretty sweet town.
Nah, that's too boring. How about "Townsville"? Yeah!
For ultra-low-budget folk, which I'm kinda assuming you are, the H4n seems to be a popular choice. But not by itself. You need a relatively decent mic (I used the Rhode NTG2). Put the mic on the end of the stick, and BOOM, there ya go (pun intended).
Now, if you're talking ultra-ULTRA-low-budget, you can always just plug a cheap $30 mic directly into your camera. This will get you better results than using the in-cam mic, but nowhere near the quality of the setup listed above.
Oh, and syncing in post is quick and easy. You don't even need a slate (clapper).
