I just found this thread so please excuse me if you have already made up your mind on this. I love KSP. Been having a blast with it. But if I had to fly missions manually without Mechjeb then I would probably delete the game. Why, you ask? Because I've been trying since version 0.16 to fly manually, and now know for a fact that I. Cannot. Fly. Spaceships. Much to my chagrin. I absolutely love designing the craft, orbital stations, ground stations, and all that, but can't fly them without Mechjeb. So putting a high price like that would make it impossible for me to use your mod as there would be no way that I could collect the 100k to purchase the thing. And yeah, I saw the comment about the Apollo computers being expensive. That's true. I cannot recall a manned NASA mission, though, that *didn't* include some sort of automatic control. So if we want to go with realism here, then every craft should be charged the Mechjeb cost, even if they don't want to use it. So in my opinion price it realistically. 10k to 25k thereabouts.
