Just wait until your bargain used Leica goes tits up and you find out you have no warranty. You will wish you had the Vortex which has a lifetime warranty, new or used.
If it doesn't work when it arrives, it goes right back. If it does work. it should continue to with proper care...it is a Leica. The particular unit I bought was very lightly used just to sight in the former owner's firearms from atop a tripod. It never underwent the abuses of a hunt. I hear what your saying about the lifetime warranty. That and price were the reason they were my original first choice. However, I've read quite a few reviews where the 1300's had problems reading half the distance advertised. I don't see any bad reviews on the Leica as far as failures. Mostly minor things like missing documentation or wrong unit sent from vendor. So I took a shot. The Leica is also 7X, where the Vortex is 6X.
