So I started flying about the world using SRTS to pick up items I needed to make the best ship in that mod and came across some towns selling the implants from Archotech++. The modpage said the items would be found in exotic ships and would be worth about 50k silver. The ones being sold in these modded towns (Faction Blender and Android Tiers) were worth 3k and I was able to find enough of the Metamorphose implants to almost upgrade all of my colonists.

I don't have anything that modifies the stock of items in faction towns, nor am I using mods that directly let me change the value of items (I'm using Infusion which lets me get up to +25% trade price negotiation at best, but I was using one with 12% in this scenario).

I'm thinking that the implants provided by this mod are too cheap and easily accessible for all of that power. If it's possible, perhaps they should be removed entirely from town shops and make them exclusive to exotic ships. Giving them the 50k price tag as mentioned on the mod page (for metamorphose at least) would make them worth the benefits they provide.
