Had my timing belt service done at ~87000 miles on my 08 SR5 V8 including water pump, radiator hoses, serpentine belt, tensioners, and I also had the PCV valve and thermostat replaced while they were there. Total labor was just over 4 hours, and total cost with tax for all the above came out to $997 which I think is pretty reasonable. I had it done at Heritage Toyota in South Burlington Vermont. They were pretty easy to deal with for a dealership service department if anyone else is in the Northeast. I'm happy to write down part numbers of what I had replaced if anyone is interested.
