Anyone know where I can buy one, or where the best price is? I only have like 1 GB left on my HD, and this seems like the best option available.
They pop up on eBay once in a while. If you're lucky, the local Best Buy or Gamespot manager may be lax on keeping inventory and they might still have one. Or you can get it from the source: http://us.codejunkies.com/Products/XB360-Xport__EF000191.aspx
