Is it time to buy a new camera?

I have a lovely little Panasonic PVGS-320 camcorder that my parents gave to me for my birthday. I did not use it until about actually a year after I got it because I didn't have any videos I wanted to shoot until then. But since then, I have misplaced the original charger and the USB cable that were included with the camera (both are needed to transfer data to the computer for editing), and have replaced them. The camera is quite old now (I got it in 2007), and I have not been able to put the videos on my computer to edit them. I can connect it to the computer just fine, and Windows Movie Maker recognizes the device and automatically asks if I want to import from my camera. But every time I say "yes, import from device," my camera starts acting funny and starts flashing the "please press the reset button" message on the screen; of course, when I do this, WMM stops the import process because the camera was disconnected. I've played around with it a bit and found that the problem is that the video camera is having trouble playing back the video while it's attached to the computer. Has anyone else experienced this with their camera? I was thinking that I'd just replace it, but I'm rather poor at the moment and would have to wait a few months until summer (I'm going to be a counselor at a summer camp and then I'll get paid). Do you suppose that my camera can be repaired, or should I replace it? If so, should I get another PVGS320 or should I switch models and/or brands? (My price range is about $100-200, and I'd prefer a Mini-DV model so that I can rescue the videos I have already recorded.)
