You can try the standards.....MidSouth, Lock,Stock & Barrel, Natchez, and SWFA
IIRC, some of sniper sites get into high end stuff
Problem is, every scope "has the best, most precision optics, superior multi-coated lenses, and unsurpassed low light capability". Doesn't matter whether it's $79 or $2,079
If possible, make a road trip to a big store that has a wide price selection. You'll see what the difference really is
