Same TT since 1987. Bang and Olufson Beogram 8002, now with a Soundsmith smmc1 cartridge. Still sounds good to me!
How often do you upgrade turntable ?
The table itself, not arm or cartridge.
And when you do, how far do you go ? Big steps, small steps ?
I got my Nottingham Spacedeck more than ten years ago and have no intention to replace it. I would have to jump high for the upgrade to make sense. One day perhaps.
