We have this same system in our Jeep, we've had it since thanksgiving time and it is very good - doesn't skip when you hit bumps and plays practically anything, even home burned dvd's - we got it at overstock on one of their daily deals - I went and looked and they still have it, http://mybargainbuddy.com/03/os10off?afsrc=1
same price as the hsn but you could go through the link here and save 7% and shipping is cheaper at just 2.95 - if you wait til the weekend to order it shipping is usually free.
Just an FYI - you can hook your video games up to it (both the psp 2 and the Xbox 360), you'll have to buy the power cord that plugs into the cigarette lighter seprate for the game, and if you only have one cigarette lighter, you'll have to get an adapter that splits it - geeks.com sells both. And you can only play on one screen, the one the game hooks up to - (the fatter one where the dvd goes in.)
Also, walmart sells really good earbuds for .98 cents. - they don't come with it.
