Thinking of a one m8 to replace my gs4.....eBay has them new for about 400 and Verizon has them for 500......would save 40 bucks in tax by getting it on eBay.....any thoughts?......or should I not even bother with the phone......I have no intentions of getting a subsidized phone and I refuse to pay 700 plus bucks so the new one is out.....for now.....any thoughts or recommendations?........thanks
