make sure you get a PAL version of the camcorder, there are shops that advertise these versions all over Kissimmee and Orlando
By buying a PAL (European) version camcorder, the majority of the famous brands such as Sony, Panny etc, the chargers are 110-240V multi standard.
All you then need is either a three pin to two pin to charge in the USA or a shaver two pin to three pin for charging in the UK.
Most of them have world wide warranties. If you go back to the USA regulary then that is no problem either.
