I recently found a Sony XL55mono. It is in an integrated headshell, like the FR-7, and is quite heavy (though not quite as heavy as the FR-7). It is a low output MC cart. I have not found specs but I would put it in the 0.2-0.5mV area. It is something of a strange beast - it has a very thin cantilever and appears to run very light VTF despite its heavy mass. I have not found any literature on it and would welcome it if anyone had it.
In any case, it sounds very nice.
Note: it has a headshell ring to stylus tip length which is several mm shorter than the FR-7.
