Well honestly, you should steer clear of the features you want. Detachable head shell, first and foremost. You're already in a budget area where there are compromises galore. One of the bigger ones, besides the bearing and motor, is the arm. So on top of that you want to add a knurled knob and threads and contacts? Fine. But understand you are sacrificing sound quality. Big time.
Connections anywhere along the delicate phono cartridge signal wire are bound to degrade the signal like you can't believe. I know. Had a Graham. Which look it up, $2500 just for the arm. Aerospace connectors. The freaking connector on the Graham probably costs about your entire turntable budget. It still ruined the sound. When I went to Origin Live, wire all continuous from cartridge pins to RCA plugs, huge improvement. Amazing improvement.
That's the "feature" you should be looking for. One continuous wire from cartridge pins to RCA plugs. Not extra connections. Fewer.
