Jazzhowell,
Ekobesky and Tketcham are both correct, as I also owned an MMF 2.1. The tonearm is the weak link, and doesn't warrant much more than the Goldring it came with. I liked it with the Shure M97, but when I upgraded to the V15Vxmr the arm just couldn't keep up. I also tried a Denon 103R and sure enough, it stuck right to the platter. It was the first turntable I ever set up on my own, so it was a learning experience.

Best to stick to MM cartridges while you have the MMF; I haven't heard the Ortofon, but the 2M line seems to get great reviews.
