I use Smitten Kitchen's version of Martha's mac:

I also skip the bread crumbs and just panko toasted in butter. Or nothing. I use mainly white cheddar (a combo of more expensive and cracker barrel style) because I am not going to drop $40 on cheese for this.
The key is that it uses a TON of cheese. I barely cook the noodles, maybe cook 1/3 of the directed time, and the cheesey sauce absorbs nicely. It's creamy and delicious. Less cheese means a dry mac and cheese!
