I got my valve cover gasket for less than half of that including shipping from Desert Motor Works, but of course it takes time to replace it.

Most rubbers deteriorate with exposure air, heat, and oils. I didn't even need to replace mine since I had no smell of oil nor did I ever have to top off on oil between changes. I probably could have gone to 100,000 miles. But as I said, it's really easy to change these out. The most exotic tool I needed was a T30 torx bit and the most time consuming part was cleaning the valve cover.
