I'm about to lose interest in record players

Are cartridges like this worth considering, or are they just cheap junk? Specs don't look too bad, but who knows?

IMHO, I see the hobby as split into two (perhaps incompatible) parts:
1. Restoring vintage consumer record players to operational condition.
2. Playing vintage records for enjoyment.

I would *NOT* be playing well preserved quality vintage records on garden variety consumer record players... My vintage Sheffield LPs are not even going to get near one of those devices.
