To be honest, Robo, I think you might need to spend a little more than that to get anything decent. It's not worth scrimping on, as a new CPU to replace one that a poor quality cooler has allowed to fry, will set you back a lot more!
Bat69 is the person to ask - hopefully he'll be about later, in the meantime, you could check out
www.chillblast.com, who offer a fairly wide range, and also do the pastes. Obviously there are other retailers that sell CPU coolers.
