Hey Dave, I have the Xacti HD2 - both love it and hate it. Not the perfect camera, but it has it's pluses. Super smallness being one of them. No audio levels being a major downer.
Here's a recent vid I took that I'm particularly proud of: http://www.vimeo.com/232062 Otherwise, check out my Live Music Journal where all the vids are done with the Xacti plus an external shotgun mic (the Azden ECZ-990). http://livemusicjournal.blogspot.com Cheers, Mark*
