I had a Pro-Ject RPM-1 turntable and if you know the shape of it, you know the dust cover for it is optional ($100) and completely separate.
I really didn't care for having to find a place for it when listening, and all the handling leads to wear & tear that clear acrylic isn't know for handling well. I'm moving to a turntable with integrated dust cover and
I will rarely remove it for play, to be honest. In fact, don't be surprised if I play it with the cover closed because my TT is placed between my desk and the window where at least two of our 3 felines go to enjoy CatTV.
All personal preference, I need to protect the machine from things (cats) that most of you don't need to worry about.
