Some things aren't available at the other, and prices can vary greatly between them. Since I am the customer, I can take the time and do price comparisons even on caps and resistors! Charlie

I guess that takes the cake. Well, it is called findchips. You have to go to findcaps.com for capacitors. I like the hack that allows you to sort by price on Digikey (using Greasemonkey). Shame they don't incorporate it themselves.

And 7,055 pcs is not "oodles." And even those are just remnants, the other BC550Cxx are non-stocked. And this only one will also go non-stocked when they are bought. And they are exactly at the same point with BC560C. 4,000 left in stock at 2x price and a big fat warning they will go non-stocked once that inventory is sold. --- ****************************************************************** * KSI(a)home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ******************************************************************
