(...) Yeah, you're right, of course :) ehehe... I would try first to buy them at an electronics shop or something, then search the web shops (...) I'm a bit electronics-o-phobic, that's why I use LEGO instead of jumping into "real" robotics, with (...) (23 years ago, 25-Jan-02, to lugnet.robotics)

You said: (...) I quite agree, but this might be a fairly safe first step... (...)
