Hi! this is my 1st post on this forum. I spent hours reading FAQ`s

so I hope I will not ask stupid questions.
I have a Laptop which I rarely use. It has a Athlion x64 1.4 GHZ CPU, 512 RAM and 80 GIG HARD. It also has a VGA out, a DVD writer and usb ports.
I want to get an in-dash LCD touchscreen with VGA as an input.
After hours of searching for the right and not too expensive LCD I found this on Ebay:

Would you suggest me to buy this LCD in-dash monitor? It seems to be very popular, since that guy got 2300+ views. I think it has no name. Thank you!!!
