Compatible Door Chimes for Ring 2

I have just ordered the Ring 2nd gen and I planned to wire it into my existing Deta C3504 door chime. I checked the spec and it ticked all required boxes. Since then I discovered it’s on the incompatible list which is annoying. I decided to check the compatible list and order a new chime, however most on the list aren’t available in the UK. Can anyone post a UK Amazon link to a unit that will work? TIA
