AVR-Chat

I have been looking for 6 pin, female, 2 row IDC connectors and flat 
ribbon cable for AVR ISP programming cables but haven't found them in 
any of my normal sources - Digikey, Mouser, Jameco.  Maybe they have 
them but I have been unable to find them.  Can anybody offer me sources 
and/or part numbers?

I have been using 10 pin connectors on my projects but am planning to 
switch to 6 pin connectors and wnated to make up a few cables for 
different programmers.

Any help would be appreciated.

Thanks,

Bob
