Look at site sponsor CameraLandNY's website to see what is in that price range. (They can export binoculars, no trouble.) They are very competitive and stock a lot of different makes and models. (They also have open box, demo stock, and factory refurbished stuff sometimes that can be a bargain.) Keep it simple so the maker is more likely to be spending the production cost on good quality components than on gadgetry.
The law of diminishing returns is very applicable to optics. It costs increasingly larger increments to get smaller and smaller improvements. $250 binoculars may easily be twice as good $125 ones but $500 binoculars are unlikely to be twice as good as $250 binoculars. A $4000 set is certainly not ten times better than a $400 set. When someone comes along and tells you need to spend twice as much or ten times as much as your $250-400 budget to get anything worth having they are often looking for validation of their choice to throw money at a problem they can't be bothered to think about or they need to show off that they have that much money. You know your budget and you need/want the best you can get for your money.
