From our previous threads and discussions, I conclude that the Minolta 7000 AF clearly offers the best chances when it comes to repairs.
The 9000 AF has more weak points, is more complex in its construction and the technical documentation is limited to the service manual.
Here is a comparison.
Minolta (Maxxum, Alpha) 7000 AF
Minolta (Maxxum, Alpha) 9000 AF
It would also be interesting to compare it with the Minolta (Maxxum, Alpha) 5000 AF, its little sister.
Conclusion
If you are interested in repairing the first SLR on the market with integrated AF and a large range of system accessories, the 7000 is a good choice. It also offers the opportunity to understand individual technical aspects thanks to the excellent documentation.
The electronics of both the 7000 and 9000 offer some options for repairs and the housings are screwed together rather than clipped together for easy maintenance.
Information about this can be found in the forum using the search function (various related threads).
