I've been working a bit with DIP28 plugs lately on an expander for the 
Miniwave.  I've found that many of these plugs are actually headers which 
are meant to be soldered to the PCB.  The pins are thinner and shorter than 
one would want to plug into a DIP socket.  They will NOT reliably plug into 
a leaf socket, but I have found them to work well in one of the machine 
screw sockets such as the Mill-Max.  Thomas & Betts had plugs specifically 
designed for plugging into sockets with gold pins, but they seem to have 
disappeared, and they don't / didn't make the 28 pin I was looking for.  3M 
has what seems to be spec wise an interesting plug, but I'm having 
difficulty locating them in quantities less than 100 pcs, and they are 
about $4.00 each at that price break level.  The nicest 16 pin DIP plugs 
I've seen are the CW Industries http://www.cwind.com/ which I've seen used 
by Grant on the Wiard modules.
