Cheap Lcd/tvs ..monitors best brands??

I am wondering if anyone knows where to purchase cheap but nice lcd headrest/visor/standalone tv/monitors. I already have an 8'' liliput for the dash but want to add 5-10 more screens in my car. Not only headrest types but all kinds..

I'm sure i could go out and buy $1000 your daddy gives you the money so who cares type screens but once again i'm buying a lot and I am going cheap but don't want crappy crappy quality.. decent would be perfect !! If anyone knows a place or a type worth getting please let us all know !!!!!
