I've bought 4 used cartridges here on Audiogon over the last few years. All have been as advertised or better than expected. I always TALK to the seller. I find out about their equipment, LP cleaning, listening habits,etc. Then get a feel for their honesty/openness.
I believe anything you buy used has some sort of risk. Just need to feel comfortable about item and seller before you lay out the cash.
