Recommended Harley rental in the USA?

I will be driving Route-66 in May and I have to rent Harleys in the USA. Since the bikes are rented in Chicago and returned to LA, it probably needs a nationwide provider. Of course, EagleRider comes to mind. Has any of you had good/bad experiences with them? Did you book directly with them online or through one of their German agents? Does anyone know Reuther Entertainments? They value being independent of EagleRider and would also have station in Chicago and LA. (Price would be about the same.) What else would there be for landlords you can recommend?
