Anyone know of any sales on Xbox 360s?

There was a compatability thread on xbox scene’s forums. Started reading from here: http://forums.xbox-scene.com/index.php?showtopic=538258

There is only 1 hardware revision of the 360 so far. The over heating issues were deemed to be random and mostly from the exhaust ports being blocked. The only difference with them is the model of DVD drive in it.
