If SAS code is an important qualification, then your best bet might be:

"SAS System for Mixed Models" by Littell, Milliken, Stroup, and Wolfinger

It covers a wide range of standard linear and mixed models, and provides lots of SAS code as well as interpretation of results. But it doesn't focus on how you should design your own experiment. There's also "SAS System for Linear Models" by Littell, Freund, and Spector. They're both available from SAS Inst. I don't know of a user-written SAS book which is better, and none of the books I would usually recommend on experimental design have *any* sample code.
