I would recommend a TS100 or TS80 over the Hakko FX-600 for occasional hobbyists. Those are both closer in design to the iFixit iron. Digital display, standard (replacable) power connectors, safety features, etc. Even more compact.
Sure, but there’s also less to go wrong with an FX-600. It’s literally a wall jack and an analog switch. No pushbuttons, no displays, no power adapters. Safety features are worth considering but everything else seems unnecessary.
I'm not a fan of devices with a built in non-replaceable power cord. With the T100 I've already replaced the cord with a longer one. I can also run it on batteries, if necessary.
