But I forgot...you want to use this for a business....I'm not too sure you wanna show up with a consumer camera.
Even if you go with with the Sony HD-1000, it's still only a single chip camera. Your client should be aware of this and/or be charged accordingly.
It might be in your best interest to get this JVC camera as a 2nd angle camera, and rent a professional camera as your primary until you can get a real one.
If a business showed up to my wedding with the same camera that my guest had...I would be pissed.
