My son is leaving for college in a week and I will have no 360 to use anymore. I used his mainly for streaming NetFlix on XBL, but game on it occasionally. I am getting ready to purchase another one, but wondering should I buy a arcade version like he had or get something else. Also new or used? I am also reading something about a "Jasper" chipset. I don't know what kind he had, but we never had any trouble with it. Thanks for any advice.
