I bought Vortex Diamondback 10x42s after having Leupold BX-1 Yosemite for a number of years. We still love and use both.
Both are way under your price range.
I personally like the Vortex more in terms of clarity and crispness and build quality and controls. I paid around $225 for it, so if you double that and look at the Vortex line, I think you'll be good to go
