I have a Mac Mini and MacBook Pro, both of which I purchased within the last 6 months. I also have iMovie '09 installed and need to buy a camcorder that integrates seamlessly with iMovie '09.

My preferences in a camcorder:
1. Uses flash memory. (No Hard drives, tapes, dvd's etc)
2. Would prefer High Definition
3. I want to keep the price less than $500.
4. Would prefer to stay away from Sony. - I've had reliability issues with their camcorders in the past.

I read that with older versions of iMovie, many flash memory based camcorders that were supposedly mac compatible still had issues playing well with iMovie. This is why i would like peoples input on what they have used and know to work well. Specific model numbers would be most helpful.

Any suggestions?
Thanks in advance,
