Hi, I'm currently using an old Logitech M570 at work and I'm looking to buy a trackball for my home pc as well.
I have a Logitech G502 at home and will likely be alternating between those two.

I'm pretty happy with the overall feel of the M750 so I was thinking about the Logitech Ergo M575 or 575S. The MX Ergo S also looks good with the ability to tilt, but it's too expensive imo.
I would like it to stay under 50 €.

One thing that concerns me is the durability of the mouse switches. I already had to replace my G502 once because of Logitech's dreaded double click problem and I'm starting to get the same symptoms on the M570. Is this something I still sould be concerned about?

Which other manufacturers or models would you recommend?
