The TW was a great turntable, and still is. It's not like TT technology has gone very far in 20 years. And who cares if it is not talked about; there weren't very many out there. A TT may age in one place and that is the bearing. Have you looked at it, or had it looked at for wear? IIRC the original was in stainless steel. When I had a bearing replaced with a sapphire thrust plate and ceramic ball and a special lubricant the performance went up measurably. Another place to upgrade might be the PS.
Then as others have written upgrade can be in an arm.
Just my 2 cents.
