hi, i'm from australia...and ofcourse everything here is PAL but i'm looking to buy a gl2 and i can get them much cheaper on ebay (i'm looking for a second hand one) but there NTSC, what are the disadvantages of having a NTSC camera in australia?

For starters, having an NTSC television to display your footage.

Many folks consider the PAL versions of cameras to be better than NTSC for a variety of technical reasons, such as the slightly better resolution of PAL.

My advice: save up and get a new XM2 (PAL GL-2) or other kindred PAL camera. It will save you much expense in equipment and analgesics.
