A camcorder from USA will output its video in the NTSC format, but in the UK we use the PAL format.
The good news though is that most TV's & VCR's can convert a NTSC signal and display it ok, but not in full quality.
If editing video on the PC then you can convert the footage to PAL before writing it to tape/VCD/DVD.
You will also need to check that the charger will work on 240V (USA uses 110V) or you will need to buy a voltage converter.
Prices in the USA are cheaper, but not by as much as it used to be and with all the problems it might be worth buying from home.
Mark.
