recommended cartridge under $300

I have a wilson benesch full circle with the act.5 arm, copland csa 14 integrated and martin logan aerius i's. i listen almost exclusively to acoustic jazz and unfortunately have run out of funds for a great cartridge for my analog deck. i do, however, have about $250-300 to spend on a decent (perhaps not great) cartridge. any input would be appreciated. among my shortlisted ones are the denon dl103r, grado sonata, goldring eroica. i'm looking in the used market (about 100 hours max usage if i find one). thoughts???
