whats your budget, and when you say "shoot at 1,000 yards" what do you intend to shoot AT 1,000yds.
I just took my dad out to 980ish today. He was shooting a 10-50, and a 3-16. I had a 6.5-20, 6-24, and 5-25 on the guns i was using. The cost of the scopes runs from about 300 bucks to about a grand, their intended usage ranges from mid distance hunting/varminting to benchrest or "tactical" competition.
Quite honestly we werent asking a whole lot out of them and making hits on the 10" plate we were shooting at, in the conditions we were shooting, was simply could you see the target well enough to get on, and were the adjustments good enough to put the bullet on after a sighter or two (dad managed to run the first 3 with his Bergara with the Sightron SIII, and put it away)
Some were nicer, some adjusted cleaner, one ran out of adjustment and required the use of the reticle.....all still did what they were supposed to. Change the condition, make the target smaller, or change some other variable and there might have been a noticeable difference.
