Ortofon MC2000 is spectacular if you have an appropriate high gain phono stage or dedicated SUT for it. I’ve been able to find unused NOS (New Old Stock) and the package is very impressive with invitation to the ortofon Golden Ear Club. This is a high compliance and extremely low output MC (can be used on the same tonearm with your grado). Ortofon MC-2000 is full or details and really a mind blowing presentation. The NOS unit can be very expensive, but cantilever and tip is so special, do not expect any re-tipper can replace it with something equal. Only the original worth the effort and money.
If you’re considering the low compliance Miyajima, which must be very interesting cartridge, you can look for Ortofon SPU Royal G mkII with Replicant-100 profile and very special coil. The Miyajima and SPU can be definitely grouped together, while the Miyajima has Shibata profile the SPU Royal G has Replicant-100 profile. However, for both cartridges you need much heavier tonearm than for your Grado. SPU and Miyajima are Low Compliance cartridges and highly regarded for their organic presentation! But with Replicant-100 profile on SPU you will get more details, really nothing to miss. And life span of Replicant-100 is up to 2000 hrs !
A good Miyajima (Kansui or Madake) is much more expensive than your budget BTW
