LF: Portable DVD

[seabird]

i am in the market for a portable dvd player to be used primarily in the van for the kids. i have seen the 7" Mustek on sale at FS, $99 I think, but found the sound not to be very good (not loud enough) so decided to hold out a bit longer to see if another deal came up.

- are there any other deals out there?
- can you recommend a player in the $100 to $150 range that has better sound or is there any way to improve the volume of the Mustek?

thanks
