I agree with agentaqua for the most part, the difference between a 100 $ pair and a 2000 $ pair is remarkable, in terms of clarity, light gathering etc.. However once you get around 500 $ the difference is noticable but to a much lesser degree. I would not get anything beyond an 8power, ( to much shake )but in the widest objective lens within your budget. When you test them out, look for clarity right across the lense, the better ones will have very little distortion on the edges.
