Danny,
You're not likely to find a camera with XLR inputs in this price range. The good news is that you can get adapters fairly cheaply, try
http://www.bhphotovideo.com & J & R Music (www.jr.com). But you'll find those XLR mics are beyond the weekly allowance of the average 13 yr old also. (Shucks, most of them are beyond MY allowance!)
You can get lav and handheld mics for 1/8 connectors from about thirty dollars and up. These will be a big improvement over your camcorder's built-in microphone.
