I own a maxxum 7. IMHO, I found this to be one of the best Minolta AF cameras produced. Sure, it doesn't have the brick like qualities of the 9, but it is a slightly more modern design, which will take the latest SSM type AF lenses. As for AF lenses, Minolta made some of the best with its 'G' range, as good as anything that Canikon produced. Sony also have the Zeiss range, which are excellent as well (but quite pricey). For more lens information, you should check out the database at www.dyxum.com. There are reviews on most lenses.
As for the camera itself, I love mine.....maybe I am being biased!
