I'm flying out to IAD in a few weeks and am on the lookout for cheap 2nd hand portable dvd players. I'm sure I can pick one up at Nurenjie for pretty cheap, but does anyone have an idea of a price range? Also what about anything specific to look out for? My price range is 250 RMB or less, and I'll even throw in some extra money for a spare battery/repairs. All I care is that it lasts me for about 5-8 hours on the way to IAD and on the flight back to PEK a few weeks after that.

Anyone have any suggestions/ideas? I've tried asking in That's Beijing forums but to no avail.

Cheers
