If your SUMIKO tonearm is moderate mass then you can't go wrong with JVC Victor cartridges. Your suggested budget is more than enough for any of these. Two of them are direct coupled LOMC (AT ART1000 inspired by this technology, watch it), but one of them is absolutely terrific MM, talking about Victor X-1II (Beryllium cantilever, Shibata stylus tip). Even lower model X-1IIe (Titanium Pipe cantilever, Elliptical tip) is absolutely amazing for half price.
Victor are state of the art cartridges in my opinion.
