Cardone may, i said MAY, put out some more under the part number
58-461 .
they were even sold by amazon for under 60.bucks.
so check the part number in your google search every few mounths.
we should do a group buy with our own CORES if we could just send them all in to them?

just an idea...
i'd even DONATE one core to help out as i have one of there rebuilt ones on my 161ci and one held in reserve.
