I think
miketodd58 has the clearest (get it?) answer. Everything I have read seems to confirm major advances in lens coating technology in the past 10 - 15 years such that you get a lot more for your $$ these days. I had an old Pecar scope that I upgraded for this reason. Sold it to a collector and used the money to pick up a new product that was a major step up in clarity.
So your Swarovski is probably not as good as a new $400 scope. But depending on what you do, it's very likely good
enough.
