I have the JVC/Victor Everio GZ-MG755 but that is not for sale in the US, but the GZ-MG555 is, and the only difference is the size of the Hard Disk Drive, the 755 is bigger.
Great camera, I like it.
But, if you are taking video for the net, put it on the economy setting, the resolution for the "Normal" setting is WAY to high for net work.
