1. In terms of video quality, is the video quality from this camera just as good as comparable camcorders from Canon, Sony, JVC, Etc … in this price range ? Is the video quality from this camera sufficient for a video business like weddings and corporate videos ?
Yes, it’s easily comparable to any of the other major brands. I personally use it to shoot corporate and live event video.
Here’s a good hands on review of the HMC150 camera:

2. I am also impressed by the 3 year warranty as other manufacturers seem to only cover their cameras for 1 year. Is this camera reliable and durable ?
Yes, Panasonic could not afford to provide a 3 year warranty if it wasn’t.
3. Are there any major complaints about this camcorder ? I have heard it has poor low light performance. How bad is it ?
I have no complaints with mine, and it is one of the best low-light video cameras on the market. ( see the review above )
4. How is Panasonic’s reputation for producing good Camcorders and providing good customer service and support ?
Panasonic was ranked the 89th-largest company in the world in 2009 by the Forbes Global 2000. It is one of the major players in the video production industry.
