i am thinking maybe to just play safe and buy a new Atomic Z2 for $500 instead of the SP MK25 used for $500 ...cant handle horror stories... enough horror already in the world....Thank you

Splurge on your actual life support equipment -- and everything else can be had on the used market, if that's to your taste, with little concern . . .
