For CLC options you have the above stated Corsair H60, the Thermaltake Water 2.0 Performer. I can't find a review comparing them though, so I don't know which one I'd get.
For standard heatsink/fan combo's, you have a lot of choices. My current favorites are the Noctua NH-U12s and NH-U14s. Same basic cooler, but the NH-U14s is a bit bigger. Both are under your budget though, and both perform really well.
Between the options listed, I'd prolly get the NH-U12s. Read up on the reviews for it though, and make your own decision as to which one will better suit your needs. They will all perform about the same, even keeping up with the lower end liquid coolers.
