Anova is all around pretty good and should be available in the EU
That said these are simple machines. I’ve been using immersion circulators for cooking since around 2011 with a home built setup. They’re just a heater, a thermocouple, a relay, and a PID controller to adjust the temperature as needed based on input from the thermocouple. Don’t submerge it and it should last ages
Since then I’ve gotten a few proper ones and they all work about the same because they’re pretty simple. My anova works well but I also have a Chinese no name one that was $13 and works about as well. A bit harder to use as the controls are weird, it feels cheap, and it can’t do huge tubs of water like the anova can but that’s not common to utilize.
Whatever you buy make sure it’s somewhat easy to clean (generally you should still clean and dry it throughly after each use, especially so if you ever have a failure where the bath gets contaminated obviously) and look into how the stick mounts to whatever you plan to use as a vessel for the bath. I generally just use stockpots or whatever for shorter cooks but I also have the plastic tubs as well and some options don’t clip on to everything well, apparently
