I doubt those small portable video cameras can do full HD nicely. I mean, the price tag just doesn't back it up. It might be good for small home videos but nothing more. Personally I'd either go with a decent mini DV camera or go all out and get one of those expensive legit HD camcorders.
My web design teacher has one of these:

and it's quite nice.
