I have exactly the same screen. The quality is good. I took the screen apart and I am about to build the screen in the wall, there is already a hole in the wall.
I bought it via the auction, it was my first buy on ebay, but it worked out very good. I payed around 135 and 17 for shipment.
Just like chak said, just install the touchscreen driver, if you are running Windows and off you go.
