Do any of you movie geeks own a portable DVD player, or know anything about them? I'm thinking of buying one (haven't decided for sure yet) but there is such a range in prices, I'm not sure what to get.

Are there specific features that I should be looking for? Are the more expensive ones worth the extra money? Mine will be spending a lot of time travelling in a suitcase, so I need something sturdy.

Any advice you can give is appreciated. Thanks.
