> What's the sacrifice between their $200 and $1400 scopes?
Brand name, reputation, QC. I find that cheaper scopes have more factory flaws, more blurry images, less reliability over the long term…. not a huge difference in performance between those numbers.
For a one time per year use, a $200 scope is not bad, as long as you overestimate what you need. Example I bought a $30 scope with 3-9 magnification, but I made sure it had 60+mm aperture because I knew the objective lens would be of inferior quality and wouldn't collect light as efficiently as a more expensive scope. If I had bought a cheapo 3-9x scope with a 30mm aperture, it would be useless right out of the box, and I wouldn't get my moneys worth. Doing it my way, overestimating certain requirements, worked pretty well for a few hunting trips before moisture got in and it broke.
I would recommend that you don't go over $500 unless you plan to assassinate archduke ferdinand, or are a damned serious collector. The differences in performance are so slight that a guy that trains every weekend with a $200 scope is superior to a guy that trains every month with a $800 scope.
