The premade 3-pin female connectors w/ wires can be purchased from hobby
suppliers, such as http://www.towerhobbies.com. Look for either servo repair
wires or servo extensions. Also, you can always rob an old pc for a very
good assortment of connector/wire combinations. But if you need a lot of
the same type, other than 3-pin, I personally don't know of a place that
offers them premade.
If you build them yourself, http://www.jameco.com has a good variety of
I've found Jameco to be a good alternative to digikey.
