That said, you can get a lot of scope these days for $200.
I've been happy with scopes from Leupold, Kahles, and Bushnell. Picked up a Fullfield II last year, and think it's one of the best values out there right now... and it got me in this photo contest (vote, please

)... perhaps you'll get in next year!

Is a Fullfield II as much scope as you get for $400? Maybe, maybe not. Depends some on what features you're after, and what your eyes think. I don't know about the internal construction of these different scopes, that'll affect durability.
