What different pieces of test gear (and leads, soldering, etc.) would you consider necessary for a hobbyist who has been into electronics long enoufh to master the use of scopes, power supplies and sig gens.
Whatever you need. If you're working on a circuit and say "Damn, I'd really like to have $X to help me with this", then get $X. If you already have the essentials there's no need to go crazy with test equipment. Beyond scopes, power supplies and sig gens, most stuff has somewhat limited applications.
