Test leads with banana plugs on one end and alligator clips on the other you can never have too many ;-) I have several sets of these and find them indispensable in the lab. I mainly use them to connect my lab bench power supply and DVM to the circuits I'm working on. They do one thing, and one thing only, very well.
