Cartridge for Michell Gyro SE and SME 309

I don't know if this will help you, but I have a Michell Gyro Dec turntable that I bought from a local stereo store. It was their demo table that was up and running, so I had the opportunity to hear it before I bought it. The sale included the cartridge, which is a Benz Micro Reference. I like it so much that I still don't feel compelled to change it. 

Just FYI, there is a Michell MC cartridge for sale here on Audiogon (The Music Room), within your stated budget. You might check it out.
