how about -10% repair cost or -1 minute re-repair time?

Either or ? I mean I would prefer cost reduction over time reduction.

+1 Lol didnt even see this here~

I'd rather have one of those than auto repair.

So here's my idea:
Dark Rootnode Bot. (can be found trough an NPC that is only available when your Dark Rootnode is open?)
Description:
This clever little robot uses (something complicated) to boost your shields, as well as adding to your hull. It also allows for cheaper repairs by hiring in black market repairmen. (or something)
Size: 25.
Hull: 320.
Shield: 140.
Decreases ships repair costs by 10%. (limit 3)
