Online or at Big 5 or other big chain sporting goods stores, you can find Bushnell Powerviews, Tascos, or similar generic compact binoculars for under $20. If they work for you, STOP THERE. If you stupidly start to ask questions like, "Are more expensive bins really 'better'?" or "What would be the Spyderco/Benchmade/Sebenza of bins?" etc., etc. -- well, you risk spiraling down a dark, dark, expensive path.
Actually, here's a tip you'll likely disregard, but... Most 'beginning' binocular users intuitively assume that higher magnification = better. However, esp with compacts and doubly so with low-end makes/models, start with lower rather than higher mag, 6x or 7x if possible, no more than 8x. Even 8x is too high IMHO, but you'll probably buy 10x anyway.

In your price range, almost everything will be a compact roof prism, but if at all possible or available, start with porro prism glasses over roof prism. (You can look up porro vs. roof for better explanation than I can provide here.) Good luck and enjoy.
