Over the last 3 to 4 years I have purchased 6 Leupold scopes on ebay, new and used. The used are covered by Leupold lifetime warranty, and have been purchased at way below retail price. The only scope I haven't purchased on ebay I purchased in Cabela's bargain cave which was like new and $250 less than the regular store price new.
That's a good choice, but pay attention to where the focus is set. I had the factory set mine for 25yd close focus, for a very small fee, but the factory ones are set for long ~100yds close focus, as I recall. You may want to think about Adjustable Objective. In any case it's a great scope. ....mike
