If I were you I would look into the Bushnell Legend line of Binoculars. They are fairly cheap(150-350) depending on what type of prism you want. I picked up a pair of 350+ binoculars in great condition on Ebay for $150.
Bushnell Legend binos pageThe roof prisms are more expensive, and the Porro prisms are the cheaper. I have a pair of each and the only difference I notice is the size and weight. The quality of glass is the same.
