Ok, just give the player a good looking over when you get it to make sure it's as advertised, a lot of ebay seller's are not honest with the description.
You should get TV-out and 3gp support extra which I don't have on my player.
The back is just plain enamelled steel like the ebay photo, not very pretty but it doesn't scratch.
Good luck with your buy and let us know your opinion of it.
