Also, if you don’t have a machine to just experiment on, swapping an internal SSD drive back and forth may be cumbersome. If you’ve got the extra 15 Euros, buy a (preferably used) NVMe-to-USB3 adapter/housing, so that you can connect your SSD externally via USB. Such an adapter is very useful anyways. (This setup is still way better than permanently using a regular USB drive.)
I think the general term for this is “domain sniping” or “catching”. From this, I also found this paid service, catches.io; can’t tell if it or dropcatch is better. They both only charge you when they are successful in catching the domain for you, which is good.
In general, I second the notion that one probably can’t get around paying for a professional, paid service, since one is up against professionalized scoopers (godaddy and the like), who have put a lot of optimization (down to the placing of their servers) into trying to get an edge over legitimate buyers and competing scoopers.
