I was going crazy looking for accessories for my PE and finally called office depot. They had a power adapter that works (still have to get it to be sure) according to the office depot tech and she ran a google search- ended up on the accessory page for entourage and said the one they sell has the same specs. Did the same with her for a repalcement stylus and she had one ($16.99) in case I loose mine;{ so give office depot a call.
