42rh prices

I had planned on doing a 2004r swap but after realizing no pick n pull had a core, I decided to go with the 42rh (A500). Now what I am finding is these places think they are made of gold.

One yard quoted me $750 for a trans that has over 200k miles, another quoted me $350 for the same mileage. I was expecting $150-250 max. They both said because it is a truck transmission it is going to cost more. I don't get it and am a little disappointed. :(
