Jelco's are well made plus very versatile judging by the cart/head-shell combinations people report using that replacing it without making a lateral move is going to be difficult. Osage Audio sells Sorane with recommendation for medium to low compliance carts but spindle to pivot distance does not match 240mm.
@noromance I would be interested in your opinion or review of a 750 with Ammonite mounting collar if you ever have to switch back over to your 750.
