We've got the W164TR 16" model, same as the W164DR but doesn't have the built in DVD. Great picture quality with wide viewing angle.
We use an Avtex aerial (SDH1000) which is amplified and powered directly from the TV, rarely have an issue getting a good picture. Sound quality is good, you can also transmit sound over the vehicles radio (built in FM transmitter) if desired. It has a built in PVR (you'll need a USB stick) and plays movies from USB too, but its a little picky with formats.
Small(ish) and light, sits on the kitchen unit or table without too much trouble.
