@kbmr As a person who has occasionally written turntable reviews for Discogs, I can tell you that reviews can only get you so far. The issue with any gear is a how it holds up in the long term, and most reviews are done in a fairly short period of time. It's unlikely that anything will go wrong.
But the sole Pro-Ject turntable I reviewed had a hum from day one and nothing got rid of it. Eventually one of the cartridge clips just fell off one day, which was likely the issue. It didn't seem to be an inherently bad product, but it was not constructed well.
If you google "pro-ject turntable problems" you'll get pages of results, many of which are identical to your issues. Motors stopping.
