Terry and Beverly Krug, doing business as United Plumbing, purchased a used 1989 Caterpillar model 225BLC hydraulic excavator from Midwestern Equipment Company. The Krugs brought this diversity action under Arkansas law, claiming a Midwestern sales representative made material misrepresentations about the excavator. They sought to rescind the contract or, in the alternative, to revoke their acceptance pursuant to Arkansas Code Annotated Sec. 4-2-608 (Michie 1991). The District Court1 entered judgment for Midwestern after a bench trial, and the Krugs appeal. Having reviewed the briefs, the trial transcript, and the other materials submitted by the parties, we conclude that the District Court's judgment was correct, and we affirm. See 8th Cir. R. 47B.
