Digi-key always seemed to expensive for my tastes --
at least for
everything that I need, Mouser seems a lot less expensive & I can attest
that they have *very* helpful and quite clueful staff, but when you need
that *weird* part, JDR & Jameco seem to keep a lot of older stuff in
stock...
I love the way Digi-Key kits their parts. That plus, 7805 and 7812
regulators sold by Rat Shack have a tendency to pop quicker when
presented with too-great a load...
