Agree they're easy to build. For a makeshift setup you can connect a function generators output in parallel with a scope. Set the function generator for a 100khz @ 100mv square wave output. The cap under test also gets placed in parallel with the generator and scope input. Basically a good electrolytic cap will short out most of the signal, whereas one that's gone open or developed internal resistance with show more of the generators signal. At least it's very educational to see the results on the scope.
