When folks are talking about returning their SP2s and getting back refurbs, are they using the standard 12 month warranty from Microsoft or is this the MS Complete or something else entirely? I just picked up a SP2 256GB from Best Buy and generally speaking avoid extended warranties, but am on the fence with this particular purchase. If you guys have extended warranties, are you going the Complete route, the retailer of choice's offering, or Square Trade? Really, it comes down to, which is the best option for getting a brand new unit if mine goes tango umbrella? Thanks!
