You ought to at least check the price at a Toyota dealer...

The expensive parts like starters, alternators, A/C compressors are available as remanufacturered parts through the dealer and with a Toyota warranty..

I've always found the prices pretty reasonable on Toyota remanufactured parts, much less than a new factory Toyota replacement part.

I've not sure if the same suppliers or reman parts are available through all Toyota dealers in the US since the US is broken up into different distributor regions/dealership..

I'm speaking of a dealer in the SouthEast Toyota distributor region above..
