The only scope I ever had fail was a really cheap impulse buy, I don't remember the brand. My rule of thumb, somewhat arbitrary I admit, is to buy scopes that are at least equal in value to the rifle. So far that tactic has worked out well.
I own several of the older Burris models (USA made) Leupolds, and lately Weavers. The Weavers I have bought have all been their upper end models but bought when I found them on sale. Their clarity and performance is remarkable.
