The long wait for X had me looking at the used 7+ market in my area. Found a Verizon model A1661 Product Red 7+ 128 G for $500, in excellent condition. Owners getting an 8+ this Friday. Should I jump on it? My 6S+ battery is dying, the potential availability and first year glitches of the X scare me a bit, a cheap 7+ for now then jump to the 2nd year X would not be a bad idea. What do you guys think?
