I've found that there are still a few very fast normal lenses on the used market for close to or less than $500: Canon 50/1.2 FD Canon 50/1.2 LTM Canon 55/1.2 FD Canon 55/1.2 SSC FD Nikon 50/1.2 AI Nikon 50/1.2 AIS Pentax K 50/1.2 (often under $400) Pentax A 50/1.2 Olympus OM 50/1.2 (sometimes over $500) Olympus OM 55/1.2 Minolta 50/1.2 Minolta 58/1.2 (sometimes well over $500) Konica 57/1.2 Others that I'm missing here? Please tell your experience with these lenses. I bought the Pentax K, which seems to be the least expensive of the bunch, and am looking forward to its delivery. I used to own the Zuiko 50/1.2. Should have kept it!
