If it is a PAL camcoder than the only thing you need to change is the power cable. If you want to buy a NTSC than you have to change the mainboard which costs around as much as the camera
Actually, the power supply says right on the bottom:
USA & CANADA 120V AC
FOREIGN 110/220/240V AC AUTO
So other than the main AC, you're good to go.
There is no reason that an NTSC camera cannot be used in any foreign country. You just can't playback NTSC recorded tapes in a PAL or SECAM deck. You'd have to rely on the camcorder or bring an NTSC deck/ monitor with you.
