I have a 20GB I'll be selling soon. It is non-HDMI, never RRoD'd, and in mint condition. Comes in original retail box with all hook-ups, 1 wireless controller, and all manuals. Even includes the original receipt to Walmart.
If I remember, it was purchased in March of 2007, so it should have 1+ year of RRoD warranty left on it too. I don't really have any games to go with it though, nor a wireless USB dongle. (I use my laptop for the LIVE connection)
