You can buy Northern Brewer's "Dead Ringer" kit which is a THA clone but it's a fairly simple and tasty recipe.
12 lbs 2-row pale malt mashed at 152* (or substitute 9.15 lbs light LME)
1 lbs crystal 40
five 1 oz centennial additions (60, 20, 5, 0, DH)
If doing extract, add only 3.15 lbs of extract to begin with and add the rest toward the end of the boil. Not only will you get better hop utilization but it will give you lighter color closer to the original.
