The rebadged are the black and silver ones. They look exactly like the Dell ones except they have a Rio sticker over the DELL name on the front face.

I personally prefer the dell receivers over the rio. The dell knob is larger than the rio allowing me to get my fingers around it better and scroll through my playlists much faster.

Get a receiver if you're on the fence they are very cool (even if you can't sync it to play the same song at the same time or stream internet radio with the central).
