I just acquired a Pioneer PL-516 and enjoying it after good cleanup and detail etc. I was looking for a 518 but got this one for $95.00 with original headshell and a ADC cart with a SLM63 stylus. I bought a new dust cover for it and belt for a total investment of $227.18. Should I be content with this one or continue to look for a 518? I currently have an AT headshell with a AT-VMN 95ML stylus and cart in it. Are they that much different and if so what? Thanks! ; )
