I would suggest that TTs, like any other component, has improved over the years. My overriding memory of the Garrard TTs is sonically very good, but compared to the current Pro-ject, pick-up a lot more "Woe and Flutter". If you are serious about TTs, then go and listen for yourself and see what you think.
Strange thing is, I've probably had turntables for longer than most people, yet I know so very little about them. This is due to that fact that I've always had Garrard until quite recently.
Brief rule of thumb: Always buy a turntable, regardless of age, from TT specialists such as Pro-ject, Rega, Thorens, Mitchell etc etc. I would avoid Pioneer TTs, JVC, Marantz. This is a plebes view, and not everyone will agree....
The PL12D has somehitng of a good reputation. As good as the CS505 that I had many years ago.
I owned a Garrard SP25 MkV or VI, not quite sure, one of the later models that was made of microphonic plastic, had no isolation and had an 'S' shaped tonearm just as everyone else was going to straight tonearms again....and it was rubbish!
