Check out the Steiner Marine model 8 x 32' s. I think they weigh 18oz and are small. They are all you will need for glassing. They also have the individual focus feature which means you focus once for each eye and you are focused in for all but the longest or shortest distances.
The problem with the real compacts like you are asking about is that you cannot look through them for any extended period without significant eyestrain.
The Steiner Marine is a waterproof, clear, glass, in your price range.
I have a pair of Steiner Hunting series. Been using them exclusively for 10 years, very nice glass. I can look through them for hours with no strain.
