If you can find a Pioneer PDV-LC10, you won't be disappointed. Only a 7" screen (that 9" on the Panny is to drool for), it has beautiful playback and a battery thatcan get you through The Godfather. It been replaced by the LC20, so if you can find it, you'll likely get a great price on it. I paid about $650 for it last year. It should be a lot less now.
I'll second the recommendation for the Panasonic. Although I haven't seen the LA95, I used to own the DVD-LA 85. It's a terrific player. I highly recommend it, and from what I've heard, the DVD-LA95 is even better.
