In full-size binoculars, if you are not willing to spend at least $500, you would be best off buying a good porro prism glass.
They are far more rugged than they are given credit for and they offer image quality that will rival (and sometimes even better) that of the so-called "Alpha" glass at prices that are much, much lower. Good options can be had from Nikon, Leupold, Pentax, Bushnell, Minox, etc.
If you just can't stand the idea of a Porro prism binocular, but still have to spend less than $500, then your best bets are going to come from models like the Nikon Monarch, Bushnell Legend or Discoverer, Leupold Cascades, Olympics, Mojave, Brunton Eterna, Pentax DCF WP II, etc. Their optics are noticeably inferior to comparably priced Porro models, but they are (usually) a little more compact and people seem to like them better.
