I have a 20x Super Sniper and a 8.5 to 25 Leupold. Yes you do get more for the money but over four times more - well that really depends on how serious you are about your scope. The 20x Super Sniper is a fine scope for a guy that shoots paper or prairie dogs or things that are a long long way off. I do recommend the lens shade.
The 8.5-25 Leupold Mark 4 variable power scope is more versitile for tactical situations and is better brighter glass at a huge difference in price. I plan to buy a 10x Super Sniper before too long so from that you can read that I am quite satisfied with the quality for the price. I do think in a fixed power scope the 10x is a more usefull better choice than the 20x for most people. Another choice that you could consider is the 6x or 10x IOR which are in the $450 to $570 price range. My suggestion is buy the 10x Super Sniper and dont look back.
