What cartridge(s) are you thinking about?
What Phono Stage?
Do you have any/many Mono LPs?
MM and/or MC, need a SUT?
I suspect you will hear differences from those parts of playback more readily than differences in the TT itself.
I recommend you get a Tonearm with both removable headshell, and verify it has arm height adjustment. Better, have the potential to add a second arm and have Stereo and Mono ready to play any second.
Rega starts with low profile 14mm high cartridge bodies, on fixed/no height adjustment arms, the least flexible.
Pre-selected cartridges____?
I highly recommend the Luxman PD444 that I helped a friend with
I earlier went with a JVC Victor Two Arm Plinth CL-P2, then squeezed a 3rd compact arm on it
The Luxman has an A/B switch to select which arm, I found a SUT with 3 selectable inputs
