I shoot cheap 8X binos when I shoot the IBO Southern Triple Crown and shoot nicer ones for ASA as that is where I concentrate a little more. If I were to get serious about the National IBOs I would look hard at the Alpine Apex. They have an 8.5x50 that I borrowed for Rome last year and man they are as nice as any of the $1200 binos and cost in the $400 to 450 range. Sorry I do not have a web page for Alpine.
Another of the lower price range brands is Opti-Logic. They are nice and no where near the price of some of the high enders.
