Hi PJ -- I am a GH2 video shooter. I got the camera with the 14-140 because I was tired of hearing Canon autofocus motors in my videos. The autofocus motor on the 14-140 is absolutely silent, and it is a great general purpose zoom lens too. As you probably know, however, at f4.0 it is pretty slow and is not an indoor existing light lens. I have studio lighting and a couple of inexpensive Canon and Konica legacy lenses for that.
All of that said, I recommend getting the camera with the 14-140 for the silent autofocus alone. I got the GH2 with the 14-140 from The Camera Stre in Calgary last Christmas for $1537.63 + $25 for shipping. They're in stock right now for $1478.46 + $25 for shipping. Or you can get it body-only for $946.87 + $25 for shipping (I don't work for these guys, but they have the camera in stock when Stateside dealers don't, they are knowledgeable about the camera, their prices are good, their shipping charges are fair and their customer service is great).
Good luck,
Bill
