Colin Ferguson, on trial for his Long Island Railroad massacre, rejected the insanity defense proposed by his attorneys. After a report from a court-appointed psychiatrist, the trial judge found Ferguson competent to stand trial and allowed him to represent himself. [Note that this outcome may have been different today, in light of the U.S. Supreme Court’s 2008 opinion in Indiana v. Edwards.] At trial, Ferguson was clearly delusional, for example arguing that the 93 counts he was charged with were related to the year 1993, and had it been 1925 he would have been charged with only 25 counts. He was convicted in 1994 and sentenced to 315 years in prison. Although the competency report is not publicly available, as far as I know, Court TV videotaped the entire trial and released a VHS tape, copies of which can still be found for purchase.
