The Dynavin makes sense, I've just heard they are buggy. That could be old news though, as the Android versions are supposed to be better. You may want to check.
But, as you said, OEM look, all the parts, great idea. I started piecing mine together (bluetooth, ipod, etc) to really keep the OEM look so I passed on the Dynavin. With a vert, I didn't want anything that looked non OEM in case of sticky fingers.
