Minolta has produced some excellent glass and the Rokkor series of lenses are superb.
I have used the 28mm, 135mm 2.8 and the 58mm 1.2 for many years. There seems to be many manual Rokkor lenses on the auction site for reasonable prices along with the 100, 101, and 102 SRT bodies. A camera store owner once told me-
"While the rest of the world are buying Nikons, the Japanese are buying Minoltas".
(I really admire, use and own some nice Zenza and Zuiko glass as well- but you can't go wrong with Rokkor lenses!)
BTW, the 135mm Rokkor lens was my favorite for shooting b/w actor's headshots.
