The 12 power can be a blessing or a curse. When your set up, the extra little power can be nice. Holding it with one hand to get a "quick look" though could be frustrating. Here are some good deals for the price range:
Cabela's Outfitter 10x42 on sale for $400 online. They are regularly $600 and are Steiner, German glass.
Doug at Camerland has a super deal on the Minox HG 10x52 for $600, regularly $1100. A little more $$$ but that would be my pick.
Cameraland also has the Vortex Vulture (older but not used) that have a slight cosmetic blemish in 10x50 for only $160, usually $250.
Or...pick up the Zen Ray ED2 10x43 for $424 and see what all the hype is about.
