Just picked up the Panasonic Portable DVD Player DVD-LS855 (similar to the DVD-LS865) at Costco and it appears to be a good deal for now. The main reason I went with that is we often need to have a porable DVD player for trips, in and out of the car, on a plane, at someone's house or a hotel, so this was the best overall solution for our needs. Otherwise I would have had a unit installed in the Trailblazer for a lot more cost. It's got some drawbacks for a solution, it's only on one headrest, the sound quality isn't really loud (at least one headphone jack though), but the picture is pretty good. It was listed for $165? and there was a $20 instant coupon, so it was about $145 overall. It has a carrying case, DC plug, AC plug, and a mounting bracket that can stay in the car. The screen is 8.5" in a widescreen format. 16:9 I think. It's got a dual-pivot screen so you can get it just about any angle that you want. Plus the battery lasts a long time, it's supposed to go up to 6 hours if you keep the screen brightness down and use headphones. I'll do some tests on the road and we'll get some more feedback over time. Looks like a good investment overall.
