Is there a reasonably priced place to buy decent quality male cord ends 110V 125 Volt

I do not always need watertight. Sometimes I just need a new end on a trouble light or something.

This is the best I've found so far:
Woodhead / Molex 14W47 Watertite® Polarized Straight Blade Plug; 15 Amp, 125 Volt, 2-Pole, 3-Wire, NEMA 5-15P, Yellow - Crescent Electric Supply Company

 

Any good hardware store.

 

In my experience most stores do not have any decent plugs
