whats the differents from these models as i am totaly confused from the models due tothe fact they all look the same apart from one is white and one is black.

CANON XLH1A DIGITAL VIDEO CAMERA

CANON XLH1 HI DEFINIITION DIGITAL VIDEO CAMERA

CANON XL2 DIGITAL VIDEO CAMERA


So what are the differents from all of them? they all look the same. Apart from one of them is white colour the CANON XL2 DIGITAL VIDEO CAMERA is white but then you have a black model the XLH1

So which os them is the Full Hight Definition ?
Which of them is really the black one ?
Which one of them is the latest and popular one ?

Sorry im just confused because i search pictures for the mdoels and they all seem to look the same unless different countries have set up different model numbers which still is the same model and feature ?

CANON XLH1A DIGITAL VIDEO CAMERA seems very cheap in my country while the CANON XLH1 HI DEFINIITION DIGITAL VIDEO CAMERA cost double the amount.
