For a good quality spotting scope under $200 you need to look at the used market, and go for quite old stuff. More Kijiji and garage sale than EE. If you find something that looks really old-fashioned with a good name like Bausch&Lomb, you may get good glass that will be of some use. It won't have the benefit of modern coatings, but if if it's good glass, it will be worth having. We use spotting scopes when we need much more magnifcation than binoculars, and magnification doesn't just enlarge the image, it magnifies the effects of poor quality materials and construction.
I got a Bushnell Sentry from Costco for $100. That was a pretty good price for that scope, but it's not a good scope. I make do while I save up for something good enough that I can be looking through it the rest of my life and knowing that while better stuff is being made, I can still see well enough that it's not worth upgrading.
