Switched from hot air to a proper desoldering gun and it cut my board repair time in half

I was fixing a bunch of old game consoles last month, mostly PS2s with bad power regulators. For the first five, I used my trusty hot air station. It worked, but it took forever to heat up the ground planes and I cooked a couple of nearby plastic connectors. Then I borrowed a Hakko FR-301 desoldering gun from a friend's shop. That thing pulls the solder out in one clean shot, no mess, no extra heat. I did the next five boards in the time it took to do two with hot air. The initial cost is high, but the time saved on through-hole components is insane. Anyone else made a tool switch that felt like cheating?

You cooked plastic connectors with hot air and the boards still worked? I would have expected melted plastic to short something out or ruin the traces. That FR-301 is a beast, but I'm shocked the earlier boards were even functional after that kind of collateral damage.

Honestly the plastic might have acted like a shield in a weird way... like it melted but formed a blob that just pushed away from the pads instead of flowing. I've seen old ABS casings warp but not really drip. The real killer is when that vapor gets on the board and leaves a nasty film that causes leaks later... that's the silent failure nobody talks about until the board dies a month later.

I used to think hot air was the only way to go for that kind of work. After seeing how clean a desoldering gun is, I'm totally converted. What's the next tool on your list to upgrade?
