Any driver with the last name Camfield. Really great group of people.

Also Rich Corson and Corson/Savage Racing. They may not have Guess money but I'll take Corson/Savage racing over them any day of the week.

I completely forgot. Even though he doesn't race the car, Ron Hemelgarn is a complete class act and is definately a low income racer when you look at his Indy 500 team.
