This is a difficult Item to buy used. You are at the mercy of the seller, unless you can inspect the stylus with a lute or something so as to magnify the stylus enough so you can see if it does any wear. If it looks smooth no chips out from the sides, it is good. If you buy one over a distance you must take the sellers word about condition.
I have not had good luck in this but you can find many in good condition, it is hit and miss. A used cartridge will have some wear and it is subjective.
Cmo, your original Question was for a 2K cartridge. The Fugi and the shelter 901 new, are within this price point. Another website;
