Help with NEW MC cartridge putchase

I am certain that this question has come up before, but here it goes again. I would like to purchase a good quality MC cartridge to go with my tube phono stage (40 db of gain). The rest of my equipment are all based on tubes and I use SET amps. I currently am using the ClearAudio Aurum Beta S model, which is a MM cartridge. But I want to experience-- hopefully towards a positive direction--the sound of the MC cartridge. I am not looking for anything that costs an arm and a leg. No more than $750. If you have any suggestions, I would really appreciate it. Thank you
