Which material is best for a cartridge body?

Thanks guys. I'm just looking at cartridges in the $200-400 range (I've got a modified Technics 1200). One thing it's for sure: must be shielded. I'm using a Grado right now and it doesn't cut it...too much hum. It sounds really nice for the money. Very musical.

The guys at needledoctor are recommending to me the Ortofon MC 15 Super MK II low output MC cartridge with Noryl body ($215.00). That is, for my Technics SL-1200 MKII (which happens to be a favorite there) and for listening to ALL types of music. They say Noryl is less bright than aluminum...that it would be a better match for my TT dollar for dollar...

I'm open to any other suggestions in the $200-$400 range...

Frogman, I've got a vintage Biotronics Gestalt low output MC preamp (and am going to have an Absolute Power Cord hooked to it next week). Modified 1200s can handle Benz Micro Gliders, no problem. The problem is my wallet!

My man at Needledoctor suggested the new Benz ACE or the Ortofon Kontrapunkt A if I wanted to step up...that basically the $215 MC15 Super MKII was nonetheless the overall best buy...

I'm still wondering about those 2.5 gram tracking forces...

The cartridge purchase has been aborted, folks! I took my car to the radiator man yesterday and it was $125 (cool). He then told me the fan is not working! Today I took the car for an oil change, tire rotation and fixing a flat tire...well the bill turned out to be $646!!! Complete brake job!!! My Proton amp is being shipped Monday (+/- $90).

When it rains it pours...

Thanks to all.
