My approach to test equipment: it either is irreplaceable or at least greatly alleviates certain operations (e.g. RF generator for alignment, or audio generator for audio amps, obviously a DMM, a variac) or is a matter of safety (isolation transformer) or saves me money and troubleshooting time (tube tester, scope).

To me the capacitor tester does neither, so it is a matter of "I just like to do it". Which is a respectable position, but not a necessary one but any means, especially for this hobby. There are situations where it has its merits.

So, if you have money and feel good about it- go ahead, there are many things we do just on a whim, cuz we feel good about it, including this hobby itself.
