Portable DVD players for kids?

All of the sudden the last three fly-in guests (with kids) we've had at
the inn have had those slick little portable DVD players attached to
the backs of the head-rests, for viewing in the plane. Two of the
three had two of them -- on on each seatback, for separate viewing.

I've watched as the price of these little gizmos has dropped to around
0.1 AMUs, and have considered installing them in Atlas for my kids to
enjoy.

For those who have them, how do you get power back to them? Has anyone
here installed a cigar lighter in the back seat area of their plane?
Would this require a 337, or just an A&P sign-off?

Can anyone recommend a specific brand? How 'bout mounting them -- any
special tricks?

Thanks!
