I want a 65 HD spotting scope for its versatility in weight and ability to reach out a decent distance. I originally was looking at the Vortex Razor HD 22-28, but after reading threads a lot of people suggest Swarovski is one of the better scopes. They have two models in 65HD including their wide 25-50 and their 20-60, however both are priced at least $1,000 dollars more than the Vortex Razor. What makes Swarovksi worth so much more? Am I really going to notice a significant difference between the two?
