Believe me...I was asking that very same question before I installed the back brace lol. So far I got $20 for the back brace and another $40 for the plugs and the vent so not really crazy amount of money invested yet. For time, I'm probably 4.5 hours into it so far. I would say another 1.5 - 2 more hours for the vent, drain and fill plugs install. A new housing with the bearing ends and four link brackets installed would probably cost at least a grand. As for the pitting, there mostly cosmetic and do not affect the integrity of the housing so that is why I decided to go ahead and use it for now. I do intend to smooth it out as much as possible though just to make it pretty .
