Thanks for your comments.
These cost me £77 ($120) all in including the dvd player from
http://stores.ebay.co.uk/Eonon.
I paid for these sunday evening and they arrived from Hong Kong to the UK 2 days later!
The quality of the screen is ok. Of course you can pay more and get better but they seem fine. Everything came well packed and worked without a hitch. Also having had a test run prior to hard wiring in the X everything seems fine.
They ship to the US and prices should be similar (buy it now may be around $350) + delivery
Good luck
