Anyone converted to refurbished Garrard from a good belt drive?

I am surprised redone garrard cost upwards to 20,000.   Looks gorgeous etc,but still..... the design seems vulnerable to noise.  If you spent that kind of money,why?  what are you getting besides maybe deeper bass?
and which company have you found does the great job?
and what tonearm and cart?   

and type of music?  classical, jazz?
thanks
