It would be helpful to know what you like to photograph and plan to photograph, especially with the macro lens.

If you want more versatility, I would look at a lens like the Sigma 17-70mm f/2.8-4.0 DC Macro Zoom Lens which has a 1:2.3 ratio and cost around $449 US at B&H.
Zooms: Tamron SP AF70-200mm f2.8 Di LD Macro; Sigma 28-90mm D macro, Konica-Minolta 18-70 f3.5-5.6
Primes: Minolta 28mm f2.8; Sony 50mm f1.4
Minolta RC-1000 remote commander
Calumet Cambo CC400 4x5 View Camera
YashikaMat 6x6 TLR
Minolta Maxxum 7000
w/ Minolta 35-80mm f/4-5.6 & Minolta 2800 flash
Minolta Maxxum 5000i
& Vivitar 728 AFM flash
Which should I get as a decent cheap 50mm prime? Minolta 50mm F1.7 or Sony SAL50F18?
Both are in the same price range, but the Minolta 1.4 is a jump up.
Sony 50mm f/1.4
I had a trio of 50mm for the Minolta/SONY mount:
Minolta 50mm f/1.7
Minolta 50mm f/1.4
SONY 50mm f/1.4
The Minolta 50mm f/1.7 was perhaps the most prolific lens Minolta ever made and while it is considered to be a good piece of glass, compared to the SONY 50mm f/1.8, it does not hold a candle in overall performance to that you will get out of a SONY 50mm f/1.4 (ø55mm) or the SIGMA 50mm f/1.4 DG EX (ø72mm). Also, bear in mind that the Minolta 50mm f/1.4 and Minolta 50mm f/.4 have not been produced for the past 15-20 years. Lens fungus grows... over time.

A Photographer Is Forever
Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.
