@ oakr ... correction
usually it doesn;t matter wht the region of the console, is as long as u're taking care of the input 110 or 220 for the power brick, i just read piece that
the 2010 mfged slim were using 135w power, code name trinity and valhalla... if by chance you happen to get a new xbox slim with mfg date AUG 2011, its the new revision code named CORONA running on 115w and i read its not prone to reset glitch either.
