I have seen it for sale for anywhere between $129 and $300, all without games.
Because the $129.00 DS lite are the later version. $300 DS Lite is the newest version and is a collectors item.
Amazon sells the older version of DS Lite for $129.99

The $300 DS Lite available from Amazon is the latest version, much smaller and lighter than the previous one.
