You should probably go through the skins over at Real first.. These days only 2 players really get skinning attention in the community though, WinAmp and Windows MediaPlayer. I used to like Real player but, due to the way they have the volume control tied to the master volume or wav volume now I tend to avoid it more.. paid for real too. But, now prefer WinAmp for the most part.
