[sdiy] IC socket reliability/0.100 headers?

[synth]

I am for machined pin sockets as well.  With etching your own boards  
the machine pinned sockets make it easy to do solider double sided  
board where the trace under the IC need to be solidered.

I was shocked to see so many people against them and bring up failing  
rates with PCBs because of them.  The new sockets are not 1970's-80's  
items.
