One thing I like for prototyping with through hole parts is Verowire pen which kind of combines wire wrap with soldering. It uses thin wire in self-fluxing insulation. You can use the pen to wrap a bunch of components that go in series without wasting time for trimming the wire to length. Then you solder over the wraps and bite off the runs that shouldn't be there (e.g. when you wired a diode you remove the wire between its contacts).
