Got myself a YIHUA 929DV desoldering pump.
Have had an eye on it since that one anon praised it so much, got it for 15€ with coins, not as cheap as that anon said (I think he said 13$) but given that it will make a task I don't particularly enjoy (desoldering) a bit less painful that seemed like a fair price.
Suction is better than I feared, close to the mechanic clones.
I don't really have something I need to desolder at the moment, so I can't say how well it works, but I'm confident it'll be better than the alternatives (both the 5€ mains powered ones and the manual pumps).
The next step up would be a 948 style soldering gun and those start at 115€, so this feels like a comfortable spot to be for someone like me who desolders occasionally but not enough to justify professional equipment.
Only fear is that the nozzle is very small, I guess that's not as much of an issue since the solder will be liquid from the heating, but it still feels like it may cause issues with clearing clogging.
