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.
