Uhm... Yea.. I feel ashamed but that IS my budget for everything...
Don't worry about it. Everyone starts somewhere, and you do what you can with what you have (or can get).
$900 is a tad low, though. I, too, have a small budget, but my very basic set up still runs in the ~$1200 range, and includes the camera, SD cards to record to, a longer life battery, a mic kit, a DIY boom, a DIY steadycam, and a very basic lighting kit. You could easily trim some of this and get down to $900, though.
As a student, you don't need much in a camera; just some basic manual controls, mic/headphone jacks, and decent image quality. There's a
lot of decent higher end consumer HD camcorders around the ~$500 range, and that should leave you just enough to get a mic kit and other minor stuff you might need. From all I've read and seen, lately Canon tends to produce the best camcorders for budget filmmaking, but eh. Really, you could even get an old Panasonic SD camera from the mid-2000's. They're likely very cheap, and unless you need high definition, have just as many manual controls.
