I don't scrap vehicles but over the years I've had to purchase ABS/transmission/main computers for different vehicles. I usually pick one up off ebay because of the cost new/refurbished. Many times the price you will get will vary greatly depending on the model. I had some early 90's accords. They are known for bad transmission computers. I'm sure with other models the failure rate is lower, so the price was lower. You just have to do some research. Many times the sellers ask for the old unit back as a core, which is something to keep in mind.
