MM Cartridge recommendation


I am in the process of upgrading from my current project debut carbon(with acrylic platter and ortofon blue) to a vintage Micro Seiki DD-5.  It will come with the stock tone arm and Micro H-303 headshell but no cart. I am looking for any recommendations for a MM cartridge sub $500?  This turntable will be used with a Cronos Magnum III powering a pair of Triangle Acoustics Comete 40th anniversary speakers.

I was thinking of a Nagaoka MP150 or 200 but have no experience with cartridges other then the Ortofon 2m line  so all suggestions are welcomed. 
Thanks in advance.

Forgot to mention the obvious and often noted fact that Nagaoka MP cartridges are MI types, not MM.  Not that there is anything wrong with that. They work fine into any phono stage that offers a 47K ohm load and at least 40db of phono gain. (A little more gain in terms of db is better, because the Nagaokas tend to put out a bit less than 4mV.)

The products of two companies always come to mind for me when it comes to MM cartridges that offer exceptional performance, consistency and value:  Audio Technica and Ortofon.  

MoFi MasterTracker on sale for $500 at music direct. I very much like mine. +1 the Nagaoka 200. I have the 200 and 500. And a little cheaper is the Audio Technica VM740ML. 

Have you thought of MI cartridges, Soundsmith Otello or a slightly under Carmen would fall nicely into your price range. The rebuilding costs are extremely reasonable when that time comes. I purchased a lightly used Carmen II about 7 years and couldn’t be happier Nice high end, bass and everything in between,
