Sorry for the delayed response guys but I have been in a terrible sad state since Nandric reminded me that I have no friends, only turntables to keep me company. I now wonder if my dog likes me...I thought she did but, who knows.
One thing is for sure, the MFG 61 is designed to be the top MF cart and the MFG 51E is the cart with training wheels. The MFG 31 series are the mid level carts. I will say a MFG 31L will embarrass some of the flavors of the week from the other thread. It is quite good. The 51E's cantilever reminds me of Hillary Clinton's cankles. That is thick! Dgob found a statement that said the MFG 61 has a hollow boron cantilever. Maybe some do but mine has solid boron cantilever with the end ground to an angle parallel to the LP surface. The stylus body is maroon/dark red in color. Body is silver. I have had mine for some time and it was new in the box with the original paperwork. It is a wonderful sounding cart. Maybe someday I can compare it to a G7. That would be interesting don't you think?
Bummer about the MFG 61 box Nandric.
