For the money, I think a Minox ZV3 would give you better glass, and comes with a lifetime replacement warranty. For a bit more, the Vixen 4-12x40 is even better, and that is covered for the life of the product from everything short of the apocalypse.

But that's not to say the Buckmaster is bad, they certainly have a good track record. Any 3-9x40 in the ~$200 range is a good choice. My thinking lately is that the mass produced names are kind of getting comfortable, and the lesser known names are quickly catching up and surpassing them in quality and value.

Just my $.02.
