There are many absolutely amazing cartridges at this price (under $750 as you suggested).
One of them is Garrott p77i from Australia (if you want new). If you never heard about this one you’d better search.
High-End classics like Sony XL-50, Grace F9 with F14 (RS14) stylus, Audio-Technica AT-ML170 OFC are stunning performers, unbeatable by new MM.
Ortofon is not the answer, especially if you want something different (better).
