I don't understand everyone saying my first films are going to be horrid.
I never said that. I don't subscribe to that pessimism, not even slightly. Your first film can be F-ing awesome! To this day, I'm still proud of my first film. But I wouldn't be proud of it if I had made it today, after years of practice.
If you picked up a guitar today, without ever having played before, would you expect to sound like Eric Clapton tomorrow? Of course not. Look, your first film is not going to be anything like the Tim Burton that you've fallen in love with. Heck, Tim Burton's first films were not anything like the Tim Burton you've fallen in love with.
Like any craft, this one takes a lot of practice. You'll have growing pains, you'll stumble a couple times along the way, but you'll probably have A LOT of fun throughout the entire process. So DO IT! Have fun, learn as much as you can at every step. Pretty much everyone on this website, though many of us have been doing this for years, if not decades, are still learning something new with each and every project.
My only point, in suggesting a low-cost used camera, is that the video quality of your first few films shouldn't be a huge concern. There are so many things you need to work on that don't require a top of the line camera that a lesser camera shouldn't inhibit you from jumping into the deep end.
To answer your question about a tripod, a semi-decent tripod is going to cost hundreds of dollars. I'd say $200 is a bare-minimum starting point. Seeing as how your budget is limited, I recommend just putting up with a POS tripod, and treat it gently.
In my opinion, you shouldn't worry about having a fluid head. Panning and tilting, on tripod, to be honest, are kind of a hallmark of rookie filmmakers. That's not to say that they can't be used for great effect. I just don't recommend using them right out of the gate. And stay away from that zoom!
I'm sure there will be people who'll disagree with me, but it is my strong opinion that your first couple of films should be composed of nothing but static shots on a tripod -- no pans/tilts/zooms.
