I've had conquest that are in my opinion better glass than the Terra's. I really liked them. Since that time, I've bought 2 meoptas that compare favorably with the conquest. The cabelas branded meoptas are on clearance right now. I ordered one last week. Great glass for the $$$
The Zeiss Conquest is a decent scope. I have two. But I think you are stepping down a notch or two with the Terra. I believe it is made in China. Don't know about the Weaver, sorry.
