Personally I wouldn't sweat the choice between MM and MC. Just pick something in your budget that suits you and your equipment. The Acoustic Sounds catalogue has a nice table for comparison of specs. Try to get clear about what your parameters are, as in how low low an output you can run and still get the gain you volume you want given your listening habits, the sensitivity of your speakers, gain of your preamp, etc.. You may find that an output of .8mV@5cm/sec is plenty. Also bear in mind that the reference for output level varies and is often not published. A little research is in order and can make all the difference if it is on the edge.
