I'm looking for a small digital camera with a few features.

Features needed:

1. Takes MiniDV tapes.

2. Hotshoe on top of the camera.

3. Has a 1/4 inch mini audio input.

The smaller the camera, the better. Anyone point me in the right direction?

Check out the old Canon ZR series. After the ZR100 Canon abandoned the 1/8" headphone output. The ZR90 was the last one to have a headphone jack. Not great quality, but small and light weight.

The ZR800 is somewhat small. It has an 1/8th inch (mini) stereo input. No hotshoe though. The only other one I can think of that is small is the Canon HV20. Mini input, and mini headphone out. Also has a hot shoe. Even then, It might be bigger than your looking for. Hope that helps.

That ZR looks like it will fit the bill. I think Canon has a hotshoe adapter so that might not be a problem.
