looking for some connectors

[synaesthetic]

I see lots of DIY builds these days with the internal hookup wires connected via small plastic connectors similar to what is often seen in commercial products and the guts of a computer.

I managed to find half of what I need on DigiKey; I found a 4-pin female connector but for the life of me (and after a half hour of searching) I can't find the male connector that corresponds to it.

Digikey is pretty user un-friendly. =/

So what do you guys use for this purpose of connecting panel components to a PCB without having to solder it directly to the board? For my purposes I need one square-shaped 4 pin connector, one flat 4 pin connector and some single-pin connectors. The pin pitch should be 0.100".

Molex KK series, 0.100 pitch.

Mouser carries them as well. You order the housings, the headers and the pins for the housings. I usually just crimp the pins with needlenose pliers and hen solder them.
