It's the same psychological issue that people
who are ok with
soldering have with surface-mount components. It's fear of something
new or different, and it's all in their heads.
I am convince that the best way to deal with such problems is to meet
them head-on. The best 'cure' for an aversion to sodleirng is to grab a
soldering iron (by the handle :-)) and solder up a PCB. 10 minutes later
you'll wonder what all the fuss was about.
