Sergey,
Like everyone else, I was impressed with your solution to a simpler solution to installing a ZIF socket. Impressed enough that I made one of my own and it works well. I'm fortunate enough to have a CNC machine so I routed out a pc board instead of using perf board. The pc board is double-sided and I routed the traces on both sides.
