Go with your name and get a square one? I switched to it from izettle because the app has more free features I needed, like tickets that can be saved and are available across devices, but I doubt that's an issue for you. I think sumup has the lowest fees, all of them have relatively cheap readers available, zettle is run by PayPal so most likely to work well with that, I've got some old readers knocking about if you want one cheap and don't mind that they're covered in grease.
Yeah, got to register a bank account and that (maybe just a PayPal for izettle) but they're all pretty similar. The cheapest square reader users the phone screen for pin numbers, although I guess most transactions will be contactless, if you want a pin pad on the reader izettle ones have that.
