[Val Clancy <valclancy@xxxxxxxxxxxxx>]

Here is the best and the list expensive source of
manufactured ( not rigged ) 2 way 9 pin splitters:
http://www.bb-elec.com/catalog/datasp/datasplt.html
for $29.95 ( shielded and ORed ). I got one. Works
fine. Custom cable available from  some cable companies
gonna cost at least that or more.
