I keep reading references to installation costs but I cannot find anywhere just what the installation costs are for particular items. For example with particular perks you can save 50% on cybernetic installation costs. So if you have a 10,000 credit cybernetic limb how much of that 10,000 is for installation?

The Cyberneticist talent gives you a 50% discount on "cybernetics and any materials used to craft cybernetics", so you'd save 5k off that 10k cost for the limb. How much the installation itself costs isn't specified and would be up to the GM.

I tend to think that the cybernetic itself is 25% of the cost, where 75% is installation due to medical professional fees (or mechanic fees if installing it in a droid). This is based off of the comparison to actual prosthetic limbs to the surgeries required to adapt limbs to them.
