Any feedback on the Nagaoka MP 30 cartridge?

I'm hoping to spend about $300 for a nice MM.

I will using a refurbished Dual CS-704, now on its way from Germany. The table has an Otrofon Super OM-10.

I see new OM-40 styli for a low as $200, and I'd appreciate any thoughts on the Super OM-40 as an alternative, since it'd be less costly.

Thanks again!

It's been years, but I had a Sonogragh/FT-3 combo with the Nagaoka MP-30. It was a nice cartridge. Full-bodied warm sound. Not the most detailed but an easy listen. Really depends on your budget.
