I'm looking to get an ATV2 and finding some pretty good deals on e-Bay. Just looking for some advice on selection. I'm seeing quite a few that are new in box, others used, jailbroken, tethered, untethered. I'm strictly using this for netflix, HBO Go, and mostly XBMC. Any thoughts on best choice? If I got one new in box and it's on stock firmware, any risk of complications trying to jailbreak? Most are jailbroken, tethered, running 5.3.
