Compatability Issue or Not? Grado Sonata and MMF 7


I have a MMF-7 Turntable and I am thinking of buying a Grado Sonata cartridge. Currently I am using a Blue Point cartridge. I read somewhere where my turntable is susceptable to hum with this cartridge, like the Rega's are. When I mentioned this to the store which is trying to sell it, they said, "as long as you ground it, it will not hum". (I ground the MMF-7 to the back of my VITB phono amp)
However, because it is a cartridge I can not return it(I would hate to have buy a cartridge twice!). It is also used. I would like to know if anyone has any experience using the Grado Reference line with a MMF turntable.

Thanx in advance for your help, I really appreciate it!

Thanks for the infomation. I do appreciate your response. I agree with both of you! I think someone on another post may of made a mistake, or, they were refering to a different mmf.
I think the issue w/ the Rega's is the shielding and with the mmf-7's motor so far from the cartridge I shouldn't have this problem if I go for the Grado. Now, if only I could make up my mind which cartidge to buy!
