I prefer the offer of a fresh recently inspected new cartridge for a discounted price.
Audio Technica: I sent my AT33PTGII in to see if it's stylus was worn as I expected.
Yes, it is worn, we have a program to sell you a new cartridge for $_____
Half the price when purchased a few years prior.
Everything new, including fresh suspension which is often forgotten, recent inspection for output specs and truly straight/aligned cantilever/stylus tip.
