used
I buy a fair amount of used Leupold's on eBay. Leupold's warranty goes with the scope, no matter how many times it's changed hands. I believe Burris is the same way, but I have no experience returning a Burris.
I buy fixed power Leupolds, even as far back as the "M8' models, and use them with no complaints. The newer fixed power Leupold's go by F-II and F-III. I also buy Vari-X-II-c's when I can get the price I want. These are older 1990'd scopes. Then you get into more recent models, VX-I, VX-II, etc. ( I think)
Leupold's model and year designations are a bit confusing, as the older Vari-X line has several renditions, each a slight improvement over the other. A bit of research should yield the last/latest of the Vari-X's, before they went with the VX-series. I think the Vari-X-II-c was the last of the breed, in the mid 90's. Research yourself before committing.
Although Leupold will fix your scope if they can despite the vintage, certain VariX models are no longer eligible for a recticle change.
