I have been away from elections a long time. I need to get the basic surface mount pop corn resistors, capacitors, diodes, LEDs, FETs, transistors, etc for some simple digital work.
Long ago there were places that had inexpensive assortments of parts in the back of magazines. The magazines are gone and so or the dealers like Poly Pac's. More recently I found things on Japp's Chip-dir mailing list and sci.electronics and they seem to have fallen in to disrepair too.
I expect that this is still a good place to ask where to find things like this.
