I bought my wife a pair of Pentax roof-prism binoculars for under $100, in the 8X42 variety, and she loves them. I sneak them out to the deer blind as often as I can, and so far as I am concerned, they are very clear, and have a locking focus, too. Her's aren't waterproof, but the ones I bought my son are, for about the same price, and it has changed his outlook on deer hunting...he can hunt until the last second now. If you are interested, I can give you the exact model number on hers, not his (they aren't here). But for my money, these are excellent, and I have had no problem in the 3 years we have owned hers.
Having said that, I have a pair of Bausch and Lomb Legacy binoculars in the 7X35 variety, and I have never seen any clearer lenses. These are old, bought on eBay, and the porro-prism type. If they were higher power, I would never carry anything else into the woods.
