modding town recoilers

Yd Freehold recoilers are currently tier 7, which make them prohibitively expensive to mod (even though disassembling them only gives a 3-bit). Modding recoilers is never any more than mildly convenient, so I don’t see why it needs to be so expensive. Can you consider lowering the tier?

[Also, I think it looks a bit weird that the tech tier for fixed-point recoilers is so correlated with the distance from Joppa. Shouldn’t they all be the same?]
