The thing about those consumer cams is it's 11mb/s AVCHD, not 35mb/s MPEG2 nor can consumer cams shoot overcranked footage (85mb/s), so this is an apples to oranges comparison.
Actually, I was referring to the HMC150, which shoots AVCHD at up to 24Mbps. AVCHD is based on MPEG4, which is a more efficient codec than the EX's MPEG2. So I would think that 24Mbps AVCHD should compare quite favorably to 35Mbps MPEG2 in quality. Now the HMC150 is hampered by a lot of things, such as shifted pixels, lack of variable frame rates, etc., but it can produce nice pictures, and plenty of guys on this forum make a living with that camera. But I digress. The reason I brought up that camera in the first place was just to point out that Panasonic does make a prosumer camera that records to inexpensive media.
While we enjoy discussing cameras on these forums, they're just tools, and it's what we do with them that counts. So as Vic and Mico mentioned above, just pick your tool and go out and make some good pictures.
