v8 is a good option but for that price that price there are really some good coolers from noctua that are worth considering ... including the NH14, also the corsair H50 is pretty good, but its edged out by the nh14 in performance in some cases. I personally use ocz freeze tim and i found it very good , mx2 is another great option to look at , i think cpu cooler finaly comes to personal peformance ... whichever looks best for ones taste is the one to buy, but if u want pure performance air cooler then the NH14 it is . As far as tim is considered a toss between the freeze and mx2 whichever you can get your hands on.
edit : just noticed the price point think the cm 212+ does a good job in that range ... there was also some true available in the market section that came within your price point. both the mx2 and feeze was around 350 when i went looking for them last.
