The Sony A1 is a cracking little camera, i have used it on a couple of occasions and was really impressed with it. More so because of the XLR attachment that comes with it allowing balanced audio recording. Plus it can record both HDV1080i and DVCAM.....

But it's a little above the budget you've listed, the cameras in that range will be more consumer orientated with built in microphone's with a mini jack input for an external mic. Chris.
