I haven't had to do repairs on modern electronics boards in recent years. The use of SMD and reflow techniques requires tools I never needed in the past. My vision is no longer razor sharp. My hands are no longer steady enough for neurosurgery. Age takes a toll. Retirement approaches. The cost differential between DIY and hiring help may influence my choice to retool or not.
I have a wonderful SMD rework station. Like you, I have more limitations than before. There were always SMDs I couldn't handle with even my workstation.
The real dig is the software. Even if you manage to change out a defective uP, chances are high that you will never have access to the software that goes into it.
