As someone who has only touched one once, heat guns kind of scare me mostly because the airflow is invisible. I have destroyed things with it and almost burned myself. It's hard for me to gauge if you have too much or too little heat on something. Too far away it's doing nothing and too close you're frying a piece, and there is no indication where on that range you are without some learned intuition.
It’s not a hot air soldering station.
After decades of using copper braid, I recently splurged for the 301 and wish I’d done it sooner. My teen kid could effortlessly desolder the button on his worn out gaming mouse with it after 30 seconds of training (me demoing how to use it).
You can buy the Japanese version, desolder 1 resistor, and solder in two replacements to adapt it from Japanese 100VAC to US 120VAC and save about $100, plus it will remind you how awful desoldering with braid is by comparison. It takes 30 very unhurried minutes at most to do the mod.
