Where to buy headrest monitors, and other car stuff

[mmx]

I saw some good looking monitors on ebay, but wanted to know where can i go to buy:

2 headrest monitor - playback only
1 front monitor - To see rearview camera(need to buy) and also the playback from the PS2/DVD i'm going to install.

Basically was thinking to buy:
2 head rest monitors (with 2 inputs)
1 front monitor (wiith 2-3 inputs) need to accept mac mini
1 rearview camera
1 mac mini (for all the dvd, internet, (i already have gps, and XM boxes) Any alternatives?
1 Switch box to connect all the input/outputs
