the guy says it's missing a seal (whatever that means) but that it plays great, and he is giving a good deal on it Just not sure what the seal does (Assume it keeps dust out of the game cd/whatever bay), and whether the thing would last very long without it. Also not up on the termnology as far as the premium/pro/elite thing goes. Is premium the new one that is supposed to be cooler and not get the RROD? Thanks
