No experience with Weaver, but I'm a fan of Bushnell Elite scopes. An option in the same price range might be the 4200 series in 6x24...

There's a variety available in both 40 and 50mm, and various reticles.

The Elites have excellent glass, IMHO, and stand up very well.

The 6500 series is probably even better, but considerably more dough.
