I spent many a summer with my grandfather installing roof turbine vents. They're in the ballpark of $40-60...makes a HUGE difference in the temp of an attic...the hot air naturally rises up on its own, as well as the prevailing winds spin them plenty fast enough that they suck heat out no problems.

The install is fairly easy too. That and, keeping the attic cooler means your a/c won't have to work so hard.
