Cant find em anywhere, apart from cheap imitations. Obs not the best needle cart/stylus ever, but hard waring and great for leaving set up in the club for the monkeys to play with. Will they return? Should i get new new cartridges? Or is there an (official) stanton stylus that isn't discontinued that will do the job just as well. Got 500 mk II's on there atm and they seem to be doing the trick, but aint gna be able to get them forever.
