Portable DVD Player?

[ipsabio]

Does anyone have one that they like that would be suitable for airplane travel? We've got a big heavy one that we use for road trips but I really don't want to take it when we fly because it weighs a ton. I'm looking for a player to keep my 4 yr old occupied on a coast to coast trip. We normally fly Jet Blue so I know if he gets on and there's not "tv" he's going to be one grumpy traveler. Thanks in advance!
