I have used Budget, it was next to Casa de Balam, but I think that little local has closed and the office is in Fiesta Americana now.
I wrecked their car and I did not take the insurance. They were very helpful and got me another car quickly. I paid the damages on my credit card (and used the credit card insurance to get reimbursed). They were very helpful in speaking with the credit card insurance staff.
I can't recall the first name of the man that was so very helpful, it was not the owner but the man that was the manager of the Casa del Balam plaza location(to the left of the barber shop). His last name was pool xool.
The rates were about the same as every one else's, but the service was superb.
