After another frustrating desoldering session I ordered desoldering hot tweezers. Because I don't know how much will I use it I bought the cheapest - Aoyue 950. The price was about 50 € with shipping.
It came with two sets of tips: sharp and big blocks. Big blocky ones looked fine but the design was so stupid that it didn't work on any component I had.
Next - I teared it apart. The insides look like normal cheap chinese station. Big ugly transformer and even uglier piece of electronics.
In the end of the day - device works, makes desoldering of some components easier. As a common tool I would recommend hot air station first but to a bigger lab - this is a good tool to have for those nasty situations where other tools are not so suitable
I also got a vacuum pen. Useful when using solder paste method to assemble PCBs. It is a small box with a speed control button and two vacuum heads. Mechanics are exactly the same as in regular aquarium pump. It uses two channel diaphragm/membrane pump to make the vacuum. Another trick I like is that they use non filtered mains to move pump up and down.
Device itself comes with different tips, but for small components it is best to use syringe tip on original nozzle.
