By the way, the Grado, TLZ is yet another bargain, priced moving iron type cartridge. You could say that the TLZ was my gateway to appreciating the potential virtues of moving iron types. As to the question of re-tipping a TLZ versus buying the Nagaoka, MP 200, I can only say that I own a new MP 500, and it is certainly on par with the Grado if not even better. But I have no idea how that compares to the MP 200. One piece of advice to the OP would be to consider spending a little more to get at least to the MP 300 price level. the MP 500 would be the way to go if money is not an object.
