Can someone recommend a really good one for me? Thanks!

To install w/o hassle: Nexus.
To use for extra cooling: Zalman.
To show off as bling, or use of you have a fan going over them, negating the whole point: Aerocool. I have yet to see how well the Aerocool actually performs, but thos tight fins do not help if it is mostly cooled by plain old heat-rising convection.
