Expect to be disappointed in the +/- $100 price range for spotting scopes.
The old adage "You get what you pay for" was never more true than with optics.
Granted, there are some surprising budget deals, but you need to look very carefully because even different models from one brand will differ greatly in quality.
I have found or seen just about every example branded 'Winchester' to be junky. Bushnell low end ones are junk, their higher end lines are better but not great. Barska and NC Star are Russian and Chinese respectively and while they do make some quality optics some of their stuff is notr worth it, so be careful and read reviews on individual models and look through them yourself.
OK, you are spending what, one or two grand on a match rifle? Spend a little on a Scope and be happy for years......
