While the phrase "you get what you pay for," didn't get popular for nothing, money DOES NOT always mean quality either!
As JB states, all that is required from a scope is clarity, and holding a good POI! I don't care what scope you get, you will always find someonethat got a lemon! The better the scope quality, the less complaints you'll hear. Again, money is not always quality, I've seen people who didn't want to buy something until the price was doubled!
