Cheap/easy PCM/CMR fixes and custom tunes

I tend to prefer the 05-08 PCMs.

03-04 are a little oddball and 09 and newer often have AAN(Advanced Neural Network) for fuel control that can be a pain sometimes.
I was thinking of trying to find an 05 truck PCM out of a manual Ram but they are very hard to find. What do you guys charge for a tune?
