From what I've seen, I'd say that the 50mm f/1.4 lenses (A, F and FA) outperform the K50/1.2, particularly wide open, but that some users like the K50/1.2's rendering qualities. For that price, if it's in good condition, it's certainly worth buying and experimenting with at least. You can likely re-sell it if you are not satisfied for the same or more money.
For myself, I had several 50s and have settled on the FA50/1.4 as the one I kept. I prefer to have at least an A series lens so as to use all the body's exposure modes and decided that AF was an option that posed advantages as well.
