E.A.T. Jo No. 5

Hi, guys.  I'm wondering if people have experience with this cartridge that they can share.  I'm looking to upgrade my cartridge, and this is one of the options in my price range, but I'm finding very little out there about it (and a search here didn't turn up anything either).  It's relatively new to the market, I think. 

Any help or information would be much appreciated.
