I keep instinctively reading the scale icons as "higher is better" and then thinking "Oh, scales. Lower is better". Then does the up arrow on the balanced scales mean "increases difficulty for NPCs and player", "increases balance between NPCs and player" or "increases power of NPCs and player"?
Another thought on balance: what counts as "balanced" can change from version to version of Oolite. That I think took a lot of OXPers somewhat by surprise in 1.77, because the majority of changes between 1.65 and 1.76 were not to the gameplay but to the game engine and framework. 1.79 makes even more changes to the core gameplay. For example, the in-game effect of the populator/AI changes should be neutral in terms of difficulty, but almost all Ship OXPs will have their balance shifted because of the change in the way Oolite uses roles ... though the change will make it easier to write balanced ship OXPs in future, too. This will, I expect, also be true of versions after 1.79.

It's difficult, but I don't think it's entirely impossible. Think of it this way: the player can make an amount of profit in an amount of time by trading between main stations. If the profit/time isn't significantly different, the prices can be "better".
So, I think it can be balanced if some or all of:
- the prices are not reliably different in a particular from the main station prices, and the two stations are significantly separated. It may then take the player several more minutes to go between the two and compare the prices ... in which time they could have made a normal inter-system trading run for a higher profit than the few credits of difference.
- the secondary station has a very limited amount available to buy and/or a very limited capacity to sell to
- the secondary station is risky to reach, which might cost time in dying and reloading, or cash in repair bills.
- the secondary station is not straightforward to find (e.g. some rock hermits)
- the secondary station has a really small docking bay, so you have to buy an Adder first.
Some of those weren't possible until 1.77, of course.
