It's hard to justify a more expensive cooler than the Hyper 212 Evo since it will get Sandy Bridge chips to ~4.5Ghz pretty easily. The more expensive coolers will only get you a few hundred more megahertz for quite a bit more money.
The Frio is black though and the Hyper 212 Evo is not. Frio looks pretty cool too to least to me. Not double the price cool though.
