Where is the best palce to purchase headrest monitors?

[Hermosa]

I just got a New 2006 GMC Crew Cab, and I want to add the headrest monitors and DVD, where is the best place to shop for these? I was hoping to get the headrests that are already modified to make for a quick and easy installation.
Thanks mucho.

I think the visual logic headrest kit is the best... Google it, they have a site...
