Scotches have a very large range of taste - Light and airy, thick like motor oil, Dry, Sweet... Do you know specifically what your intended recipient drinks? If we knew that, we should be better able to pick.
Personally, my long running favorite is Balvenie 17 year, sherry cask. For a more special bottle, Aberlour A'bunadh is exceptional, and most people seem to like it a lot. But it's near the top of your price range. Glenmorangie Signet is also exceptional, widely liked, and in your price range.
One of the distributors made a very nice chart. Of course, it only covers what they carry. But others who may make suggestions could also use it as a reference.
