I pulled up a board I did last year and it had over 300 pins, and 
about 25 thru holes.

I had laid it on a piece of styrofoam, very thin stuff from packing 
and stuck resistors into the foam.  Soldered and nipped.

I just check an old Pentium... something.. 300 pins.  all soft and 
bent too easy.  that means to me they would be more messy than 
resistor leads.

I have a collegue who uses 22ga wire, strips off and uses that.

I would like something a little less home brew, but every time I 
look, resistors keep comming up as the best source.
