I bought my wife some Nikon prostaff 10x42 for birding and she loves them. Not to big and heavy but comes with decent glass. What ever you buy you want to make sure all surfaces are fully coated. The coatings are very important.

"Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."
