I suggest you buy a good budget TT to keep listening. This comes with preconfigured cartridge, plug and play.

Also pre-mounted cartridge

I used one of these for years, comes with cartridge, I changed it to my cartridge

Sound’s good enough, done!
If wanting better:
Repair tour existing TT
1. find someone to overhaul it.
Can you remove your Tonearm from your TT?
2. find someone else to repair just your Tonearm (easier shipping to and from)
b. buy an arm the same length spindle to pivot that works with your decks hole and thickness.
How are your cartridge mounting and alignment skills?
