sensor cabling

Hi,

I am hooking up sensors to a project and was looking for suggestions. I have seen 3.5mm stereo and mono jacks (2 & 4 wires) and was curious are people just cutting up old cables or is there a source? (I did a whole bunch of searches on amazon with no luck. Any ideas?

which country?

Mouser seems to work. I can't seem to find connectors on Sparkfun.

U.S.A is the country.
