btw, if you look at the picture from the first post, can someone enlighten me why are the IC sockets like ones in the middle (circle whole for the IC pin) 10x more expensive (and called "quality socket") then the ones that look like those on the right (two metal strips between pin from the IC slip in)... from all my (not big) knowledge of mechanic, the second ones (the cheep ones) should provide better contact ?! (yes the round ones have "sturdier" pin's but .. again .. I do not get it...)
