At what price range do you start to get to the point of diminishing returns? Realistic gains in performance. Glass quality, quality control, tubes, turrets, seals, coatings on glass, finishes, ext. Are there real world advantages to spend 2,000 dollars for a scope. I don't want to over spend, but don't want to under spend eather. I want what everyone wants, a good quality, clear & sharp, dependable scope. But I don't want to have to sleep on the couch. I'm looking for a variable, 18-24 max power. AO. fine cross hair. Any suggestions would be highly appreciated. Thanks all. :)
