mike them up with a decent lavalier mic.
I really want to avoid getting into this situation, I want my client to be a little surprised I went to the trouble to do this, but at the same time I don't want to carry too much gear and spend too much time. I think having a little atmosphere of the room may even help the effect I am try to achieve.
The Zoom looks like I really good starting point, it even comes with a nice case so I can just throw it in my camera bag. I haven't been able to find anything to beat it at the price point, I just need to decide if it's worth the punt or not.
Cheers
Cris.
