I can't comment on these specific carts/styli.
But, I have looked at a replacement stylus a few times in the past, and the cost of the stylus vs. the price of a new cart never made any sense to me! I guess if a new stylus for an iconic cart was the only option, then it makes sense.
But, case in point, when the Shure M97xe was announced to be discontinued, I looked into a stylus price vs. the full cart, and bought the full cart.
