To say that any one camera is good or bad for "filmmaking" is impossible to answer. A lot of the answer to your question depends greatly on what you plan to do with the finished product.
IF you're content with making small movies that you will only show to friends and family and upload to be viewed online, then really any camera will do so long as you are able to deal with the acquired images and sound in post-production... meaning, you have the computer or editing facilities that can handle the format you use. The more complicated the camera (ie "24P"), the more complicated your capture and editing software needs to be.
However, if you are thinking larger than that and you wish to truly work toward building a career as a "filmmaker" (meaning: Director), then you're better off NOT spending money on an inexpensive camera. Instead, invest that money into writing software and a laptop computer so that you can hone your skills as a great screenwriter.
Once you have a decent script that is worth your time and the time of others, go out to your community (your school, the local universities, nearby professionals who work in film or TV production) and look for volunteers who are anxious to work on an indie movie. There are people out there who want to specialize in Camera just as there are those who want to act. By finding these people near you who want to do those jobs, it frees YOU up to concentrate on what YOU really want to do (ie. direct) and it means that your movie will benefit because there are aspiring "experts" in those aspects of filmmaking who want to do their own jobs very well.
The Cameraman/woman you find will likely already know more than you ever will and will help to determine the best format to use to "film" your movie. If you find the right person, depending on where you live, chances are that this Cameraman will have access to lights and cameras and quite possibly, will be able to get all of it donated so you wouldn't have to spend a dime on rental (although you may have to pay for insurance, depending on the source). Going about a production in this way gives you more and better equipment and people than if you throw away money on a cheapie camera and hoping that some people will want to help out.
So, if you really want to buy a camera just to "goof off" as a learning exercise, don't spend too much money on it. When you're serious about making a quality movie (in film or video), then recruit specialists who can help you create a movie that is good enough to be entered into festivals and be used by everyone involved as a "calling card" to get real paying work in the real world. Those people are out there. You'll be pleasantly surprised at how many will be excited to help you make your movie.
