I too bought a W203 comand unit from some guy who was apparently in Lithuania. As far as I remember, it turned up within a week and was in mint condition.
However, I had heard stories of the comand units being nicked from cars and having damaged connectors on the rear where they were ripped out. So before I purchased, I asked the seller if the unit had any marks or damage anywhere. He said no so I bought it.
Only thing was, I fitted it in the summer and once it started getting dark I noticed the "Video" button seemed slightly dimmer than the others. No big deal though.
