[Ham-Mac] Keyspan adapters

[Slater Tubman]

I have not been able to locate a local source for Keyspan brand USB- 
serial adapters and have successfully used 2 Dynex brand adapters  on  
my Powerbook to interface via a Rigblaster Plus to my Elecraft K2.   
One adapter is used to the Rigblaster, the other from the Powerbook  
to the Elecraft KIO2 port.  It all seems fine, so I am wondering if I  
am missing something by not having the Keyspan adapters.

Any advice happily accepted.
