Build a kit T12 station into your own case? I took that route, reasoning that if the clone tips were junk I could install a real Hakko tip and get all the benefits of the real thing. The T12 tip combines tip, heater and temperature sensor in one unit, so costs more, but should be more accurate and consistent. (So far, the clone tips seem to work just fine.) I built mine to use an external supply, so I can run it from a battery pack or a 19V Dell laptop power brick. (Wattage at 12V seems just fine for most purposes, though.)
Or, there are versions with an OLED controller built into the handle: https://www.ebay.com/itm/294499213317
This is more convenient for portable use, cheaper, and no assembly required.
