I have used a Gaugemaster Prodigy 2 for about 15 years and I'm very happy with it.
But Gaugemaster are based in the UK and Brexit makes that difficult right now, especially if you have yo return the system for warranty work. If I was starting now I'd go to https://www.modellbahnshop-lippe.com/ and order either a Lenz or Roco system.
You could even pick up a starter set which includes a perfectly good controller for €250 AND you get a loco and coaches you could use for another project or sell of.
