The Kowa scope is popular and it is a good scope I have one. I wanted an angle eye piece to keep the scope low so looking through it did not strain the neck but more importantly keep the scope low to keep the wind from blowing it over. My old scope is a 40 year old 50mm??maybe 60mm Redfield but it is a lot sharper scope then the 82mm Kowa. Shooting off the bench I use the old redfield because I can see the holes in the black that the Kowa wont let me see. Just recently I wanted a lay down scope to read the mirage and seeing the spotter and use it for a hunting scope I could carry in the pocket or pack so I got the 15X-36X little Burris. It is a very sharp and bright scope ideal for what I want to use it for but the eye relief falls off fast a well as the field of view as the power increases but at 15-20X the range I want to use it in it is a great scope ever for a short range bench scope.

What I would suggest is go to a store like Cabela's or Shields and personally look through these scopes what ever you can afford in your price range, they will go outside with you to look through the scope at long range and shadows at long range and look through that scope to see if it has a ghost ring or edge distortions and get one that is fog proof and water proof when your using it outside in bad conditions.
Just because a scope is high priced does not mean that it better then a scope at a lesser cost. Eye relief and exit pupil
