Rifle Scopes : What general-purpose scopes are 'tough?'

The riflescope business seems to me to be a lot like the over-the-road truck business in this way: It seems very much like there are FAR more scope brands out there than there are scope manufacturers (shall I say assemblers?), and it seems as though all the brands have a finite and reasonably small number of components from which they may choose for the assembly plant(s) to combine for them. This ends up resulting in relatively small trade-offs at any given price range, with differences being primarily 'ergonomic' (to include customer/warranty support) in nature.  There may be an outfit or two who, like Mack, make a decent amount of their own stuff, but it seems to me that most of it is just picking this engine, that transmission, that cab & chassis, etc, and bolting them together.

Kinda ironic, I think!
