Yeah, Micro Center is weird. Most stuff is as overpriced as you'll find at any brick and mortar computer store, but then they'll have tons of loss leaders. I got all my components at Newegg except for the CPU its self, which was $30 cheaper at MC than anywhere online.

In case you decide to put Tomato on your new router (which really is the reason to get the L version), just know that it's really easy to do. You can find it here.
