Use is important but often not considered. I've never had my Leupold's fail - none of mine are less than 7 years old so I can't speak for new ones. Used Leupold's sell very reasonably, are considerably lighter than the high end variety and fit well for probably 80% of the folks here. By all means, if money is no object, get the best that suit your needs. I carry my own rifle in the mountains and an extra 2 lbs is not desirable. Yes, I have a Zeiss Victory and have never looked through a clearer scope - but it isn't taken up the mountain. For target, varmint and hunting stand shooters, a high dollar, heavy scope may be the ticket. But I can't help but laugh when a fellow shows up with a sub-5 lb, short barrel rifle and has a 3 lb, long NightForce on it!
